Audacious

I've been using Audacious as a replacement for Winamp for a couple of months now since i moved from Windows 7 to Fedora 16 and i must say i like it.
It plays every MP3, OGG or XM file i throw at it (non-free MP3 codecs required) and can be fully skinned to look exactly like Winamp. Don't be fooled though, it's not Winamp! Some of the plugins are good extensions to Audacious of which i couldn't find for Winamp.

• One difference between Audacious and Winamp: It can't be docked.
• Crossfade plugin problem: Bitrates must be the same between tracks.
• MP3 files: For some unknown reason it can't update ID3 tags and it doesn't have tabs for ID3v1 and ID3v2 (unlike Winamp).

I've used Amarok, Totem and even VLC in the past but -being used to Winamp and all- Audacious has my vote for best audio player on GNU/Linux systems.

Audacious is a very handy lightweight audio player for the Linux desktop.
Its powerful engine provides excellent playback quality of many formats and codecs.
The playlist manager works just fine and has some good features. Audacious does not include a media library.
The looks can easily be modified using Winamp Classic skins.
Many plugins offer extra functions like an Alarm, Crossfading, Last.fm-Scrobbling, audio effects a.m.m.
Some basic visualizers are included.

Seems very similar to foobar2000. It's simple yet it has a lot of customization capabilities.

I like it's minimalist approach. It is simple yet efficient with a nice and intuitive UI.

Audacious for XFCE is lightweight, and plays audio files, and has a built in equalizer.
Parole is a multimedia player, that can also play audio (no equalizer) and on some files sounds better without having to 'tweak' the sound with an equalizer. I notice it is not listed as an alternative, and should be.
I have both installed.
