Beatmap Listing » Chemistry meets m-flo - Now Or Never

Already did the first Astro Boy intro, so here's the second one complete with video. Chemistry and m-flo both seem popular here, so hopefully people will have fun with this one.

EDIT: 3/19: Tweaked Normal and Hard to be a bit easier.
EDIT: 3/20: Improved timing, placement, and difficulty in all versions.
EDIT: 3/29: Improved timing and reduced difficulty on Normal and Hard. Will follow up with an easier Insane and better note placement.
EDIT: 3/30: See above. I still feel that the timing is a little off, though.
EDIT: 4/08: Added recommended BPM and toned difficulty down a little more. Also added a version without video.
EDIT: 4/09: Toned down the artificial difficulty in Insane a bit.
EDIT: 4/14: My last edit took the star off, so bumping with a few more tweaks to Insane for ranking reconsideration.
EDIT: 5/06: Added and subtracted some notes from Easy and Normal, tweaked sounds and placement.
EDIT: 5/07: Fixed Easy so that it ends at the right spot instead of going for the whole song.
EDIT: 5/08: Fixed the placement of a few notes per Saturos's recommendation.
