Music Education Apps for Ipad

I've just done a round up of my favourite Music Ed iPad apps
Pretty hard to get to the end of the list, but it's a start.
Most specificly I'm interested in import and export particulars.

How easy is it to create, re use and share music files.
Does it inspire me to play more or find out more?
Or is it an engaging game  that teaches on the sly?
Appshopper is really helpfull as it helps you track app prices,
and alerts you to apps which are free for a certain length of time.
its also a good place to check for new apps.
So if you are interested check out my list here.
