Don't waste your time or money.
I signed up hoping this site would be a useful source of lead sheets. The samples looked pretty good, but when I actually got the subscription, I found the songs to have several errors - missing chords, incorrect chords, incorrect chord placement, etc.
Worse than this, when I asked to have my account closed, I was given the run-around. The Internet "whois" data on this company is sketchy, and it's starting to feel a bit like a scam.
