It really does ALL of your conversions thanks to all its assorted plugins.

If it's AACs you've purchased from the iTunes Music Store you have to either burn them to a CD and rip them back as MP3s or capture them as a digital stream while playing (using a tool such as Audio Hijack Pro on the Mac). Before iTunes 6 you used to be able to remove the DRM and convert to MP3 using iTunes itself but no more (at least for now).

does aac > mp3 sound as bad as i'd think?  (lossy  --->  more lossy)?

Lately, I've been playing around a lot with taking wave forms from comprssed tracks, subtracting off the original track, and seeing/hearing what's left.  In my experience, it seems like you loose a little bit going from lossy > lossy, but not nearly as much as you did in the original compression.  So if AAC is bad, AAC>MP3 will be worse, but not 2x as bad.

(Again IME) you lose very very little if you transcode at a higher bitrate, going from say 128 kbps AAC > LAME aps MP3.  When the sample is simple to being with, the compressor doesn't have to throw as much stuff out.

If your running an iPod why worry if it's universal? I only make 'em for myself and only play them in iTunes so I've never really cared. Plus, I think the VBR AAC files sound much better anyway. Just my thoughts
