Best Bands of all time - in no particular order

the best bands of all time.

In my opinion, the best musicians were in the 70's. So, considering this, here is my top bands of all times

1. The Doobie Brothers
2. The Eagles
3, Lynyrd Skynyrd
4. Little River band
5. Styx
6. ACDC
7. Journey
8. Foreigner
9. Bad Company
10. Black Sabbath (with Dio)
11. Scorpions
12. Led Zeppelin
13. Beatles
14. Chicago
15. Steely Dan
16. ZZ top
17. Metallica
18. Pink Floyd
19. rush
20. Def Leopard

Not to be the first to disagree, but did you really just put Black Sabbath (with Dio)? Ozzy was far superior with the band, not to mention his solo bands he put together were top notch. Randy Rhodes and Zakk Wylde are 2 of the best rock guitarists (some would even put Jake E. Lee up there as well). I like a lot of your list, though. My list will be a little more heavy with some more recent bands (I love good guitar):
