Aaaah ok ^^
3-4 hours on MTVMG is fine, I think, though, altough the PC version is a bit harder it seems. 4 hours is what I take to make many of my songs under it. This program is so easy and fast to use that it takes so few time to do anything that sounds good. On Sony ACID Pro and Magix Music Maker, I take days to create a decent sounding song (altough I liked ACID Pro quite a lot)
