I'll pick one from each album:
If I Had (Hard to do, SSLP tracklist is flawless in my eyes)
Remember Me (Sticky Fingaz sucked massive amounts of penis. RBX is pretty suck too.)
When the Music Stops (Em is pretty underwhelming on this one, D12 was D12)
I think SSLP has the strongest tracklist out of the three. Every song seems essential.
