To be honest these two songs are the demo songs I hated the most for some reasons. Idk, they seemed a bit too basic to me, but I guess it's because I am more into hardcore and eurodance. But again, this website makes all demo songs sound crappy and basic, especially with stuff by Pillagemyvillage, Quade, Madnessxiii, audioghost, etc.
I guess the artists probably didn't wanted their songs to be released worldwide or to be featured on shitty MTV music television channel, which would probably have tried to claim the rights of the song. Lot of ppl hate MTV lol, I never understood what MTV had to do with MTVMG1. I know about the licensing deal but they didn't even added anything to the software. As for MTVMG2 all they have added are samples from popular artists and demo songs from them. They weren't involved much in it as most stuff was from Music and Music 2000 and Jester/Codemasters
