The output is even more impressive when you consider the fact that except for a few cases, it was all Corgan (no collaboration on writing except for Iha's songs and Corgan famously played everything but drums on "Siamese Dream"). He definitely deserves props.
No rush on getting back to me with those song ideas. I'd rather you take some time to familiarize yourself with them and possibly twist and distort them. I've been meaning to do more stuff too. Have a lot of lyrical fragments I could send you as well, if you wanna try writing music to them (could leave them as fragments or give them some sorta rhyme scheme).
