I’m no iTMS fan, but the new features included in iTunes 7 make me want to consider using it as a librarian more seriously. Right now I use iTunes 6.x for podcast subscriptions (synched to my iPod Nano) and occasionally for streaming to my Airport Express. I prefer to use Winamp with the excellent Remote Speakers plugin to stream to the AX, though. I use Foobar 2000 for everything else. iTunes 7’s gapless playback and Cover Flow features are the most compelling to me. However, my workflow might still be convoluted in this scenario: rip/encode/tag with FB2K/Lame/FreeDB, load into iTunes library to index & get cover art, and hope that FB2K and iTunes don’t mutually destroy ID3 tags. We’ll see.
