The following is still unsorted
- Music Plasma: http://www.musicplasma.com/ - very pretty related artist mapping database with audio clips; very little documentation so not sure where their data comes from

(please add any more you know of)
The above are all general purpose music databases that we have considered working with (well, not Gracenote!). There are probably hundreds of specialist ones like:
Examples of a more tightly-focused database that is crying out to be built on top of a MusicBrainz foundation:
- Sample FAQ: http://the-breaks.com/ - tells you "who sampled what from who", irregularly updated and with a hand-tooled vibe but very interesting
- Commercial Breaks & Beats: http://www.commercialbreaksandbeats.co.uk/ - UK television advert music database
- Songtitle.info: http://www.songtitle.info/ - US television advert music database
- Some random guy's CD collection: http://www.ludd.luth.se/users/h-son/cd/info.html
I think a certain type of person would love to have their CD collection info on the web, all nicely hyperlinked and with daft statistics. Maybe listing recent additions to the collection on their weblog like people list books they're currently reading or what they're currently listening to in iTunes.
- Echo Cloud: http://www.echocloud.net/ [not working] - database of related artists (if you like xxx then you might like yyy) based on crawling P2P networks - Down as of 2008-03.

- Music Recommender: http://recommender.ipsi.fhg.de/music/cds.aspx - database of related CDs (if you like xxx then you might like yyy) based on crawling music playlists Down as of 2008-03.
- http://www.moodlogic.com/ - proprietary, fingerprint based. mood and genre matching "Effective March 3, 2008, Macrovision announces the end of life (EOL) of the Moodlogic music management and recommendation software."
