Alas, being out of college for the summer has drastically diminished my productivity, creativity, and time on the computer in one, and the prospect of further parodies seems quite unlikely. So to wrap up, here's my list of works in progress. Some of them are no more than titles, some of them I'd quite like to finish, but here they are regardless:

BZP Lovers (Back in Black, AC/DC)

Parody City (Paradise City, Guns'n'Roses)

Yes I Am Still Alive (I Can't Drive Fifty-Five, Sammy Hagar/Portal mashup?)

Donor of a Frozen Heart (guess )
