For music, I use Kagu(mmm, kinetic scrolling is so tasty) and kilikali for my .ogg's.
I used Canola for a while, and it's solid. I loaded up UKMP and didn't care much for it for some equally intangible and arbitrary reason.

I still check out the new versions of all the media players, just to see if my preferences change with the updates. They're all impressive in their own right, and for being products of the community, even more so, IMO.

Does Kagu play .ogg? It sees them fine, even fetches covers and band images for them, but silence is all I get when I try to play them. I assume that they aren't currently supported, but that the player is aware that it's a common audio filetype, anyway. If they work renamed .mp3, I'd rather not bother, lol.
