I have to say they're interesting tracks. Good to see that original production isn't dead...
Some feedback:
Speedway:Good track. It does what its supposed to do.
SUVee's: The hook could use some work. That main synth sounds like its out of tune with the voices. But that's just me.
I C U move: Careful with that Pharell impression in the hook. Some people might call you a biter... Otherwise, its a decent hit that the clubs can play.
Warning: A hot, hot track for cruising your local boulevard or main street. Not good for the club, it'll get people more crunk than they should...
Hold u down: Very creative. I love how you incorporate the sample with the lyricists. Though its kind of odd that the singer(s?) can sing about putting some holes in you and make it sound hot.
Maybe you can have your guys subliminally put in a rhyme about the 'Cube/Nintendo in the future?
