Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

I bought it a long time ago even though I already owned Loopy on my iPhone first. It wasn't even something I had to think about to justify.
what @boone51 said. If you don't own this, own it.
Plus, @michael could really use the money since beating out ANGRY BIRDS on the US app store. Also, LoopyHD is only #4 in the US appstore's music apps category. Help the guy out.
