Most linux distributions only come with one or two media players, MPlayer and VLC. Personally, these two applications are sufficient to handle my music — until I found out that there are more players available out there like XMMS, Amarok and Rhythmbox to name a few. This article describes music players that are available on your favorite platform (Linux, what else?!). What was not mentioned is Songbird, a relatively new player that is fast gaining popularity. I just wish that iTunes is already available on Linux.
Don’t forget about Banshee.
