Hi, the replays were way too slow, the screen pumps were smooth, but you need to work on syncing the speed of the replay on the bass/snare/beat of the song.
You need to get Twixtor (if you don't have that already) RSMB, Magic Bullet Looks, trapcode and sapphire for cool effects and all that jazz.
When you get twixtor, don't put the keyframes right on top of each other, but rather 4-5 frames apart when there is a sync point and 9-12 frames apart after the initial speed up
Try to not show the very beginning of a replay, I tend to start 1/4 of the way in so it doesn't do that split second of stillness.
Try to get more angles in your keyframing (lower to the ground, more rotation, try and do key frames every 100+ frames so it isn't jerking all over the place).
Good luck amigo.
