Deadbeef uses less resources while playing music than foobar2000 does on complete standby. I'm curious if it's just the Wine overhead, or because my foobar install has way too many plugins in it.

In any case, it seems I've settled on Deadbeef as my Linux music player. Since it was build to copy/emulate foobar, there are a few things about it, like how it handles rating or columns displayed in a playlist, that makes it a good fit to use in parallel to foobar.
