Summary: This game was unique from the other singing games I've seen. First, for most songs it plays the actual music video in the background while you sing. Second, they actually have a section for vocal lessons. Third, you can choose whether you want to sing lead or background (or if it was a duet, you could sing whichever part you wanted). Yes, the pitch gauge is very sensitive, but I didn't find it as bothersome as some of the other reviewers.
Summary: So fun! Be warned, the microphones aren't very loud so we cranked the t.v. up, and since we were drinking.... blew the speaker out on my t.v. Songs are fun and I've had a great time playing it!
