A few things to note:

First, I removed the old model layer, including Genre. All loops that
used the Genre enum now use a hashmap declared above the loop.

Second, calling .create() on a DAO object will currently not work, only
.get() and .getList() (and getBands() for Show) will work.

Third, DAOs are searching have not yet been created; once we figure out
the issue with actually POSTing to the server.

I think that's it. Let me know if there are any issues, I'll check my
email every so often.
