My music right now is a mishmash of old stuff mixed with weeb crud and random songs I find here and there, but a few bands that I either grew up with or like nearly every one of their songs include:

DEVO, a personal favorite I grew up with and still love
System of a Down (Sugar used to be my favorite song for a while)
Fatboy Slim with their super catchy and nostalgic upbeat techno-ish style
The Prodigy, another techno band but heavier with some rap/rock going on
The Beastie Boys purely for their nostalgic and fun music

And some runner ups:

Crystal Method (more techno)
The Chemical Brothers (…more old techno)
Oingo Boingo
Pendulum (Can’t say I like all of it but their stuff is good)
Rob Zombie
Talking Heads (nostalgia to the max)
