Disappointing "tinny" tone and lack of vocals, but good lyrics reference

I appreciate having the words to the songs. It was nice to be able to look up the words to "The Muffin Man" after my son came home from preschool trying to sing it. However, I only came across one song in which there was a voice singing the song. Its more like karaoke than sing-a-long, in a sense, except theres no indication of when exactly to start singing the words. For some songs this is obvious; for others, I could not quite get the lyrics to match up with the music as played. Finally, although it is nice to have the words right there in front of me, the music itself had that annoyingly tinny "midi" tone. I will probably not throw this app out, but only because I will use it as a reference for the words to songs to which we already know the tune.
