Who do you think the best bands are? Of all time, or of the moment. I think the chemistry of a band is important to consider, because it's kind of like a machine. If all the pieces fit together, the groove is gonna be there, and it'll be music to your ears.

Also worth considering is a band's longevity, and how much shitty material they've put out. That's why I wouldn't put a band like Pink Floyd on this list, because they released an album full of animal tracks. FUCK... THAT...

My picks:

Creedence Clearwater Revival may be the best band ever. They fuckin' rocked, and only made a finite number of albums, but EVERY track is great. The same can be said about Led Zeppelin. Those guys never had any dud tracks. Or at least a mere handful of mediocre ones at best.

The Rolling Stones never disappoint me, either. They've released a lot more material, which gives them more room for error for the harsh critics, but I tend to like all their tracks. They have so many goddamn hits! The Beatles got a little more druggie/weird with some tracks, but they're otherwise almost on par.

Another thing about these bands is that they didn't change their core lineup much, if at all. It's all about that chemistry, and these are generic examples, but I still fucking love these bands. There are probably a few other great examples out there, but I can't think of them right now.
