Possibly the greatest power ballad that Steven Tyler ever penned, "Dream On" was the second single of Aerosmith's 1973 self-titled debut. Reminiscing over the parts of his life that have passed already—and the power of what else he dreams of accomplishing—Tyler's throaty falsetto at the end of this track helped catapult the band to rock 'n' roll stardom. While acknowledging that death could be only a day away, the song encourages a "live for the moment" attitude that feels inspirational on every listen. Unfortunately, that mentality ended up inspiring Aerosmith to do Olympic amounts of Lebanese cocaine. But, you know, c'est la vie.
