Scooby-Doo! Music of the Vampire

I don't know where Imdb got the description for this movie, because it's nowhere close to the plot. What it's really about is the gang heading to Little Bat Town for a bat-themed vacation after they get an invite from Vincent Van Helsing, a less than famous horror writer. During a performance from a vampire loving theatre troupe, it appears that the soul of a real undead bloodsucker has broken free from his coffin. With various clues and suspects lurking around it takes a while to solve this mystery. The overall plot was pretty good, but the music was a little overdone. It kind of seemed like a last-minute add-on to get people's attention and wasn't really necessary.
