I can't buy songs *sulk*

Hi,

I got the following error whilst trying to look for info on buying a song (url: http://www.songza.com/a/buy?title=Mat...[MTRVPR007]):

Notice: Undefined offset: 1 in /home/songza/songza/code/songza/application/buy/C_Application_Buy.php on line 9

As a side note: PHP?! After all your amazing work with Python for Enso, I thought you'd be using TurboGears/Django/etc.

Thanks,

Darren
