I'm a performer, and I'm looking for an APP that will allow me to play my tracks through my iPad, while scrolling the lyrics as the music plays. I've tried OnSong, but Im apparently not getting it. I cannot get the song to sync with the Lyrics, and play from a playlist. ANY SUGGESTIONS???

Looking for something along the style of EmCee Pro if you're familiar

There is only one app I know off, which plays songs while also highlighting the notes it is currently playing: Symphony Pro

I am not sure what your other expectations are for this app, just take a look at the website, it may be what you are looking for.
