Bruce Springsteen will always be number 1 on my list, but I recently got into a few new bands so my current top 3 are:
1.Bruce Springsteen and the E Street Band
2.The Black Keys
3.The Rolling Stones
Some others I love are AC/DC, Guns and Roses, The Beatles (No shit, I know), Disturbed, some Linkin Park, Wu Tang Clan (Not really a band but still), old Eminem (I grew up on it), Tyler the Creator, The Heavy, some Green Day, some Radiohead,Johnny Cash, Elvis Presley (again not really a band but still) The rest is just a jamble of bands that I only like 1 or 2 songs from so I won't even bother with them
