This may be pretty neat....hopefully it works anyway.
I'll pick 2 bands/artists, and then give MY opinions of a) who I like more, b) who was "seemingly" better/more talented overall, and lastly c) who was more influential/important to music.
Finally, I will end the thread by naming 2 bands/artists to be compared for the next thread writer, to respond to the criteria above, who in turn will name 2 bands/artists for the next thread writer, and so on and so on.
For instance:
Marvin Gaye vs Stevie Wonder
a) Stevie Wonder-like him more of the 2, not that I dislike Maaahvin
b) Stevie Wonder-more talented
c) draw maybe?-perhaps slight edge to Stevie being more important/influential
