Groove Music

Honestly I think this app is quite good for managing and listening to locally stored music libraries. I've never had a issue with it scanning and adding all my music to the app. I just go into settings, tell it where my music collection is, and it adds it all. It's all organized and labeled correctly. Has album art for everything (including collections I put together my self and added my own album art to). It even auto downloads the covers to some albums that itunes can't find the cover for.

Functionality wise it works perfectly fine. It's fast, easy to navigate, looks nice etc. I really don't see what there is to hate. It seems to support plenty of file formats. Most of my stuff is MP3 like a lot of people but for the bands I REALLY like I have FLAC files and it handles those just the same as well.

because it is easy to play song

There's not a single good reason to use this program. Since you're on this website, I strongly recommend that you consider the alternatives.

Alright before you roast me because of my star count please consider what I have to say.

Groove Music is preinstalled to every Windows 10 PC and of course, being from Microsoft and all, it has always been shamed and compared to its predecessor WMP (Windows Media Player, which is obviously discontinued and its painfully not optimized and has not been updated since 2009)

To be honest, there are some benefits to using Groove Music:

1. Now that Groove Music Pass has been discontinued, it is actually a pretty clean music player
2. The UI isn't that bad and honestly it looks pretty nice.
3. It's probably the one of the best windows media players out there as of time of writing.
4. There were articles that Groove Music was actually the best music player in terms of performance and battery consumption (in fact, it even surpassed VLC). However, I can't really find the articles that I have mentioned now.

Of course, it has its cons. And there are a lot (though for me, I can only list a few):

1. Due to its simple design, there is just not much functionality.
2. NO VISUALS LIKE WMP (Man I swear that was one of the main reasons I was so stubborn to leave WMP)
3. It is from Microsoft, of course I have my skepticism about privacy and stuff

To sum up, Groove Music is a decent music player. It just works. But it won't suit the taste of those who want more functionality and for those who don't like Microsoft in general.

Microsoft Groove Music service has been discontinued.

it is Preinstalled on Windows 10 but it runs very slow and often timed out, it also has spammy message of groove music pass

Now that Groove Music Pass is being discontinued and music is being removed from the Windows store, the only viable options left for Windows phones are going to be streaming music services like Spotify or the tedious and expensive route of buying music from other stores like iTunes and then importing them to OneDrive so that they can then be streamed through the Groove app. It's sad to see such an unrivaled service discontinued, and even more sad to have no alternative for buying music.
