Seriously, guys, help me to find this song. Not so long ago I heard this song on a page of one dude at myspace, but now it is changed and the dude doesn't reply me
The main line is in the title.
The song starts with something like "u-haha-haha, u-hahaha' *trombone samples* 'um, yeah, mary jane ...'
I guess, it's in raggae/hip-hop genre ... it's a collaboration song (there are parts of dudes and a chick's part).
