Crap.
I usually try to remain objective in my reviews, but seriously... this is bad.

It is not hard to deduce that I use foobar2000, but I would honestly recommend Windows Media Player (I will get to the OS X version in a bit) over this.
It is expensive, buggy, slow, restrictive... the only reason to use this is if you have an iPod... Oh wait! Amarok and Winamp have native iPod support and foobar2000 has support via "iPod Manager for foobar2000" And just in case you don't like any of those, just go here: http://en.wikipedia.org/wiki/Comparison_of_iPod_managers

Albeit, I can say from my (limited) experience that the program does run smoother on Mac OS X, but it still either can't register or sometimes even deletes metadata (Artist, album, cover art, etc.). The store is still more expensive than Amazon mp3, the files you obtain still have a DRM code (which limits conversion, use, etc.) and if you put music on an iPod using iTunes, you cannot transfer the music from the iPod to another computer... or even the SAME COMPUTER after reinstalling the operating system.

Also if you are older than 13, they can sell your personal information...

So please, don't use it. Seriously.

i don't like it anymore, i think they should change the way it manage my content on the phone.

I use it (owning iPods, now an iPhone) but i certainly don't like it, my experience with it on windows has been one of a buggy and forever changing interface, an inability to open & other open formats properly (flac,ogg,etc), heavy memory and cpu usage, and massive updates for a media player (although they have shrank recently - they used to be near 100mb). Frankly unless you want it for syncing a device or your using mac os I'd recommend pretty much anything else.

iTunes is possibly the worst media application out there, probably second only to MediaMonkey. On the surface it' looks like a slick app, but ultimately it's poorly organized, seriously lacking in features and a system resource hog. I could understand its popularity in the past when Windows Media Player became ultra-bloated and the ultimate music app foobar2000, had a high learning curve that understandably turned a lot of users off, but now that the user-friendly Songbird has grown into a stable, well-developed alternative it's staggering that anyone is still using iTunes.

i have had iphone for such a long time and i like using the itunes to put my music, manage my apps and everything

Maybe its a silly question, however there is a mess in other forums about that. I didn't find the way to add midi melodies ti iTunes or to convert them somehow to listen. It looks like iTunes just doesn't recognize files?

Thx to this page, I finally found a great alternative to iTunes that runs on my netbook without slowing down everything! Started to sync my iPod and iPhone only with this tool and will soon (waiting for iOS 5) :) uninstall iTunes from my Desktop. Thanks again! Oh, what I'm talking about? -> CopyTrans Manager

I'm been upgrading everything to ALAC and wondered if there's a quick way to select all old mp3s for deletion because a superior ALAC version exists.

Hi all I don't know what do you have aginst iTunes it's a perfec program for what it's meant to do, not talking about windows iTunes but mac ones, and for all ur comments are right for windows version.

From Wikipedia:

In June, 2010, Apple updated its general privacy policy for the iTunes Store and iOS4 supported devices, revealing that it could and would collect real-time location-based information on users ages 13 and over. The revised policy states that Apple has the right to share this information with 3rd parties who provide services to the customer, including advertising and promotion services. Apple also states that "it may be necessary" to provide this [real-time] information in response to "requests from public and governmental authorities within or outside your country of residence or if [Apple] determines that for purposes of national security, law enforcement, or other issues of public importance, disclosure is necessary or appropriate"...."Additionally, in the event of a reorganization, merger, or sale we may transfer any and all personal information we collect to the relevant third party." The revised policy does not make any distinction between warrant-based and warrantless searches, nor provide what criteria would trigger the sharing of personal real-time information with government entities, nor allow an opt-out for the location-based information.

Need another reason to do not use iTunes? here is: Winamp.

I tested it on Windows and Os X and it is the same program, it's seriously lacking of features and format support (no wavepack, flac, ogg vorbis and stuff). It also doesn't have watch folders, is really bad when it comes to advanced tagging (no tag from filenames, no multiple tracks renaming via patterns and so on). It's a good-looking program with half the features of the the competitors.

This program also managed to kill the metadata of too much songs in my library and some tracks were lost forever and impossible to retrieve anywhere these days because they're too rare.

If you want a really complete library manager, try helium (my favorite) or mediamonkey. These are not free but worth the money and in conjunction with tag&rename (paid) or mp3tag (free) you will be ready for any eventuality.

On OS X, iTunes is pretty good. I hate bloated apps in general, but I wouldn't use anything else for music playback. I like the design and the OS integration - I haven't yet found a music playing/organising app that works better.

My only gripe is that dragging large numbers of tracks to disk (ie exporting from the Library) can be slow.

I am always surprised when I hear negative comments about iTunes from Windows users. Ignoring the possibility of plain-old Apple-hate (polarity of opinion about Apple seems to be fashionable these days), I can only imagine the Windows version must be inferior.

Dreadful piece of software. Doesn't do anything well. Slow, clunky and restrictive - when will Apple let it's customers decide what they want to do with the software? I'd like to say something positive to show some balance but I can't actually think of any way that this software is better than most of the alternatives. For goodness sake even Windows Media Player is better and that's a painful admission. Designed to sell you stuff. That's all.

iTunes was and always will be better than WMP as it is not owned by the worst company in the existence of the world
