I've tried winamp 2.91 on my ubuntu machine, it worked so great. I've listed 5k songs with no problem. It was so fast at first songs. But later when I click a song, program played song like 0.5 sec later. But I've put these songs o my NTSF hard disk, maybe that would effected, I don't know surely. Also, effects & other things worked great. simply say it's gold.
