Good but could be great

Nice collection of beats. Great for practicing to to play along to. However, it wont keep playing in the background. You have to keep the app open. Just when I got the perfect time/beat for a tune, it just stops when I switch to OnSong to pull up the chart. Would be great if the app would keep playing in the background.
