Ha, you guys are awesome. I grew up playing the hell out of this game and always found the boss songs to be awesome, but they aren't really songs I can blast in my car, much to short for that.
Skolar, really like what you've got so far, can't wait to hear the end result. Here's a video of the level and boss itself, don't know if that'll help inspire you or not, but either way.
The boss fight starts at 1:01
Kanohi, looking forward to seeing what you do with the song. Sadly all 3 songs are really short, which is what ultimately cause me to seek out some remixes for them, no better place for that then here.
Boss 3 starts at :53 seconds in on this video
And in case anyone wants to see Boss 2 it's :47 into this video
