mhmm I'm sure I heard this elsewhere too. I felt too lazy to check through my 5000+ songs on DVD+R/CD-Rs XD and I have over 25 CDs of hardcore I swear
I see what you mean though, the melody is definitively from MTVMG because it is the exact same riff recorded from the program and used in another. It's awesome though, one of my favourite happy hardcore song. It would be easy to recreate the song in MTVMG, altough it would take a while since the original is 7 minutes long.
EDIT: Hey, after looking at the H2BH pics it definitively came out here too. I think it was chapter 4, 7 only though
