Database and tools for validated BPMs of songs?
I'm a bit picky about ensuring that all of my music has the proper tags in iTunes. I rip all of my music from CDs or purchase it by the album from Amazon, this provides good coverage. I then use Get Lyrical to add in lyrics information. What I'm missing is a good source of BPM information. I've tried various programs such as MixMeister BPM Analyzer to calculate the BPM of music, but they're never quite right (There is no way the entirety of Metallica's Black album is 128,000 BPM).
