I've been thinking about switching to Ubuntu full time, but there are still some programs left behind that I haven't found any equivalent to yet. Does anyone know of a music player similar to Foobar2000 (I've read it doesn't handle well in WINE)?
It is an extremely customizable music player, and should support most of the features you are looking for. I'm not sure if it will match foobar2000 100%, but at least it should fill the gap :)
Maybe you are happy with audacious a lightweight skinnable player that can be extended with many plugins.
Wikipedia has a Comparison of audio player software which could be helpful.
Amarok seems to be a decent match functionality-wise, but it probably depends on which features are most important to you.
Honestly, I've been in the same position as you for years, looking for a comparable music player to Foobar2K in linux...
MPD & GMPC is good, as is gmusicbrowser... clementine is coming along nicely, but nothing can take the place of foobar for me, and thankfully with the newer builds of wine nothing has too - try installing winepulse from the ppa here https://launchpad.net/~c-korn/+archive/ppa.
Listening to Foobar 1.1.7 on Natty right now, and it runs flawlessly :)
DeadBeef is actively developed and in a way that brings it closer and closer to Foobar2000.
(what it lacks in Foobar2000-features (numbers of addons) it compensates in being light and up-to-the-point - the most straightforward and non-bloated music player/handler I have seen until now in Ubuntu).
With File browser plugin:
With Infobar plugin:

For the static portable version it is
Considering problems of incompatibility and other issues in using the plugins, see this related answer
To convert audio files, see this question+answer.
Considering memory use, Deadbeef is much lighter than other players that might be considered foobar-like.
The latest versions (now 0.6.2) bring it even closer to foobar by the 'Designer mode' feature (similar to the layout editing mode in foobar) by which built-in or plugin features (file browser, infobar etc) are integrated to the interface:
File conversion is now very close to Foobar2000's - see the link above on conversion.
Already mentioned in answers, a great alternative is Clementine.
Foobar 2000 itself in Wine:
The image above that shows the use of 92MB of RAM is related to the use of a 270 GB media library. Otherwise, Foobar2000 in Wine is very light even with many addons.
But even in this case it looks lighter than very recommendable Ubuntu native players and it is not heavier than it used to be in Windows with the same addons installed.
And what about it's version without manually added addons and naked interface ? It looks extremely light!
Also, considering the looks of Foobar in Wine, a good method of improving this is:
1. enable font smoothing - fire one after the other these lines in Terminal:
(select third option in terminal)
2. install a windows msstyle file in Wine/Configure Wine/Desktop Integration
3. increase the screen resolution in Wine/Configure Wine/Graphics
It comes to smth like this (but colors and fonts are customizable):
