The only artist for me would be Bruce Springsteen. Not that I can say I followed his whole career or anything, given it started long before I was born, but it's a familial thing for me, and I love damn near everything he has done. There are so many bands that I could list as a tie for second, and I guess that's why it has to be Springsteen for me, as he's the only one who is ahead of the rest. I only realized recently how important his music was to me when someone asked me my favorite song and I immediately said Racing in the Street by Springsteen, then they asked me to list a few more of my top songs, and I had nothing. There are tons and tons of songs I love, but I think that Racing in the Street is the greatest song composed in the past 50 years.
