i stumbled upon jajuk while searching for nerd-config settings for ubuntu's default rhythmbox installation--just need to rip my remaining CDs to a decent quality level. (turns out that's hard to do.) jajuk has introduced perspectives (people familiar with the eclipse ide will understand what that is), which is exactly what i requested from the apple itunes team a year or two ago at least. it also appears fairly mac-ish and i'm a mac wannahaver. sounds fairly promising, eh? not so. there is no amd64 package, though i'm sure i could donk that into existence.
but it's probably not worth it. even though they bill the software as an itunes replacement, it doesn't even rip(!). i'm now on to atunes.
