Wow, good call Floyd! I look up chords and lyrics all the time, and somehow this site never came up in my searches.

I especially like the way it formats the chords in exactly the way I'd need to enter them into BIAB. At $42 a year subscription it isn't a bad deal for somebody who is in a band (ie making money from his/her music and learning new songs all the time)

One VERY intriguing feature is that MIDI download. If it is sophisticated enough to separate out the parts into a piano track, drum track etc... and the parts actually match the song... that alone would be worth the price of admission.
(has anybody tried this with Melodyne multitrack? I need to give that a whirl)

IMHO, there are advantages of using the ACW to extract chords from an MP3:
1) when finished, the chords are already in BIAB, and don't need to be typed in
2) the same process that extracts the chords also tempo maps the song

Disadvantages of using BIAB to replicate a song is that any MIDI or audio tracks generated would be based on the style used, not the signature riffs in the song.
