Quodlibet seems fairly close to "cross-plattform foobar2000" (depending on what exactly is important to you of course)

Good call! I actually landed on this one the other day after looking more into my options. I hadn't realized before that tag editing is available from within the app.

Have you tried XMMS? https://en.wikipedia.org/wiki/XMMS

I have- it's definitely a good mimic of Winamp, but it hasn't been updated since 2004 which makes me a little hesitant.

Maybe Banshee. It meets all of my needs. It's a little heavier than I would like, but it seems to work flawlessly for me.

Agreed. I've tried several on Ubuntu and they all fall short.

Try Lollipop. It's the best I've found, next to QuodLibet as someone else mentioned in this thread. The only places it falls short are not being able to edit tags directly, and having to click 'update music library' every time you add something to your monitored folder(s).

my needs are minimal but VLC has covered my needs.

Audacious gets very close.
