Has anyone tried and tested any of the music that claims to help a baby sleep - does it work?

I have tried out alot of lullaby style music but it seems a bit too melodic and interesting to truely send you off into a deep sleep. My two favorites right now are baby rock records who do rock music but for babies and sleepymusic.com who do more trance-like relaxing music.

Love to hear your thoughts as well
