Greatest Hits: 90
This guy is simply a master of the soulful, acoustic guitar genre. He's put out so many great songs, and is a pioneer of the era. Each song has great melodies, and if you don't like Tom Petty there is something wrong with you. I'm not a huge Tom Petty fan, so I think for those who aren't hardcore should invest in the Greatest Hits album. Hardcore Tom Petty fans are kind of scary, but for the occasional listener it's great.
