If amarok or rythmbox make you feel its not for you then its the time to look up to YouAmp a simple and fast music player for linux.The name YouAmp is definitely inspired from winamp for windows, but does not seem to have any relation with it.

Youamp simply offers essential features of an audioplayer, but lacks support for scrobble tracks. For all Ubuntu users out there, you can install YouAmp from commandline. Issue the following commands :
sudo apt-add-ppa repository: rojtberg / youamp
sudo apt-get update
sudo apt-get install youamp
If you are interested in other simple audioplayers, audicious is a perfect choice. Audacious is fast and even have support for winamp themes.
