Comment on Tangerine!

The Filter almost had me with its quick results, but it's worth the wait for Tangerine! to analyze your library...

-- The Filter seems to do a more surface skim, picking based on "other people who listen to this song listen to..." Last.fm type of system (in fact, it seems they're collecting listening data to their site),

-- while the Tangerine! analysis seems to dig deeper, giving playlists with more of a constant mood/vibe.

After a head-to-head, I had a way more interesting listen from Tangerine!
