They're similar, but not identical... i think it's jsut a case of them being "hot" fonts... like popular in marketing... SS and ITMT are most similar, but if you look at the "a"s you'll notice they're different... It's hard to tell with GOS cos it's all in capitals... It's different from the capitals from ITMT, but that's not to say ti isn't the caps version of SS or something...
I'm holding out for the new album to be in an ironic Courier New font!
