Just thought I'd mention that starting from Winamp 2.80 OGG support is bundled with standard and full installs... making it easier if your friends use Winamp.

My personal opinion is that OGG is better than WMA at similar bitrates. Besides, WMA has imaging problems at ANY bitrate I tried (in the past), so I never used it for anything. I could be wrong, as it's been a LONG time since I did anything with WMA.

My only real gripe is that Audiogalaxy doesn't have an OGG search.

Now vote for OGG!!
