I always enjoy any music that gives me an adrenaline rush, whether it be rap, rock, disco, or even video games. Whenever I hear something I like, I look for a way to apply it to one of my shows. (Click the link below for more info; contact me for even more info.)

If you've played Sonic the Hedgehog 3 for Sega Genesis and have seen the dubbed Mon Colle Knights, read this. Even if you haven't, read it anyway.
Assuming that Mondo and Rockna get an extra hobby of lip-syncing or idol-singing, the songs from Ice Cap (Act 1) and Endless Mine would make great songs to add lyrics to. You should know which instruments would be replaced by whose voice.
Too bad lyrics isn't one of my strong points. Maybe I should submerge myself in a lot of music from now on. The only song I ever thought lyrics to (and only one verse) was the Hammer Bros. theme from Mario Bros. 3:
"Mama's gonna cook you tonight, daa-naanaanaa, daa-naa
Mama's gonna cook you tonight, daa-naanaanaa, daa-naa
All the fish are singing, a-long with me, daanaanaa
Mama's gonna cook you tonight, daanaanaanaanaanaanaa"
