Ever since 19.3, i've used the Celluloid that comes with it by default, and i'm a fan. It has played countless albums of lossless music and occasionally MP3's as well without a hitch. I've also used it as an aide for making .m3u playlist. No complaints here.
Music playback is audiophile quality. Offloads processing from cpu to hardware well. Very low noise and no errors, hiccups or bugs. One of the best playback programs for Linux.
Doesn't work for mp3 files, It hangs up. Several error windows, removing.
