I have two theories on music and below, I'm putting them both up for argument. So argue away. :)
1. Had he lived to a ripe old age, Hank Williams would've been considered possibly the top songwriter of all time. As it was, he died at age 29 and look what he wrote and sang. He had 35 songs in the country top 10 and his skills were still developing. I heard someone say that they saw him write the classic "Kaw-liga." Said he was in a cafe and wrote it on a napkin in the time it took him to eat.
2. Had he lived to a ripe old age, Jimi Hendrix would've reinvented music as we know it. His skills with a guitar were amazing for that era and he wanted to learn more and more. His talent was boundless.
3. Okay, I said two but here's one that binds them together. Both Hank and Jimi would be appalled by a lot of what is passing for music these days.
