Donny,
This is what I think you'd like:
https://itunes.apple.com/us/app/anytune-pro+-slow-downer-music/id478293637?mt=8

If you use the iPad in Landscape mode, the playlist stays up while the graphic window to the right shows the progress of the song playing. You can set it to NOT advance after a track is played, and it remembers tempo and pitch changes per song. It will display a lyric if you desire as well.

Highly recommended.
