Since we're on the topic of music players, I'll comment here that the lack of foobar2000 on Linux is frustrating. I don't have the wherewithal to contribute to a port, the maintainer doesn't seem interested, and things like quodlibet and deadbeef just don't hold a candle.

That said, if foobar2000 had been made cross-platform initially, it may never have been very good. Who can say.
