ok
not sure if you know this but your songs are only coming out of the left channel even on Hi-fi
the "something" that is lacking is a cohesive drum pattern
meaning your percussin and main kicks and drums do not follow a set pattern on some of the songs
and im guessing you are using fruity loops?
because all of those sounds, sound like the pre-rendered ones in that program
try downloading some new .wavs or sets
peace
