Once it finds you, you'll never escape...
Any game that has really good music is going to get stuck in my head at some point or another, but older games with their simpler, catchy melodies are the ones that stay stuck and never go away.
The one game whose music always gets stuck in my head for no apparent reason, though, above all others, is the Super Mario Bros. 2 music. At least a few days out of every week. I don't know why, but there you have it. Some of the Mega Man X stage themes are pretty constantly in my head, too.
I think the music from Streets of Rage 2, Fez, Freedom Fighters, and Teenage Mutant Ninja Turtles III: The Manhattan Project are the ones that get stuck in my head and come up the most.
That TMNT game has particularly underrated music. I never really hear it talked about but it's truly outstanding and so catchy.
Super Mario Bros 2. Specifically when I would get the invincibility star and then warp to the dark dimension for bonus coins. The music would only play that way when you'd do that specifically. I thought it was awesome and sometimes me and my cousin would sit there and listen to it.
Soooooo good. And it was on the Genesis! This was so far ahead of it time in terms of what people were doing with game music back then. I wish I could have been there when Yuzo was djing a club in Japan and played the soundtrack. I would have been so hype!
Dude yes. This games soundtrack is in heavy rotation on my iPod. That main theme is just unbelievable. He is doing some show in the US in January someplace too not sure where though.
A couple more here. The first hit me hard as a kid. While it's basically a bullshit "it was all a dream!" ending, it did somewhat gloss over the fact that the American SMB2 was terribly inconsistent in design and mechanics from the classic SMB. Plus, seeing Mario that close up was a thrill in the 8 bit era. I tend to like simple things executed well, and the gentle transition from the bombastic regal march during the defeat of Wort (was that his name?) and the ensuing celebration to a musicbox rendition of the theme felt right. Still does a little bit:
Then, of course, there's this. Which got me PUMPED. DRAMATIC ROBOT HAIR.
And, I've never thought of this before, but it mirrors the end music pretty well. Helmet on, fight, kill, helmet off, retire in the countryside. It's even similar in structure.
