I looked, there was only one other thread, and it was almost two years old...

I have checked everywhere for sheet music for the opening and ending songs to Generator Gawl, and have not found one site that has the sheet music for those songs.

The songs are:

"I Want Out" as performed by Yuki Saga and "Kore O Koi To Iemashou Ka" as performed by Yoshimba/Yoshinba.
