The lyrics on the page don't match up to the music. Sometimes it works, but it seems more often than not the lyrics are a full measure behind the actual music. This can make it extremely difficult to drive because you're always trying to find where the lyrics are. And it's designed to where you can read the lyrics along with the music in that you cannot scroll up to the beginning of the song without it automatically scrolling back down to where they think the music is. It's very frustrating. One of these days, if it hasn't happened already, someone is going to get into a wreck. They don't care about safety and they don't care about people dying on the road.
