Those aren't our only choices, right? If so, I'll cast my vote for music that has more meaning than, "lean wit it"
Led Zeppelin
Led Zeppelin is easily one of the best bands ever. They have a number of great songs and their music has some interesting lyrics and meaning that I find addicting. Stairway to Heaven is STILL heard all the time on radio stations and their other songs like Kashmir, Immigrant Song, and Rock and Roll are tremendous. Great band, blows modern rock bands' music out of the water.
Queen
Freddie Mercury, when you add Deacon, May, and Taylor...yes! Bohemian Rhapsody isn't the only amazing song of theirs either. Freddie is one of the best lead vocalists of all time, and they had amazing songs, many of which you hear often today (You're my Best Friend, We are the Champions, Another One Bites the Dust, etc.) Queen is simply amazing.
The Beatles
I could babble on about them, but everybody pretty much knows why the Fab Four are so great. Great group, plenty or amazing songs, great harmony...how great they are!
AC/DC
You hear them once, you're addicted. I actually find them all a bit overrated, but great nonetheless. There's nothing quite like listening to Thunderstruck or TNT at incredibly high volumes!
Elvis Presley
Long live the King! What's so great about Elvis is that he wasn't just a rock singer, but could also do other genres incredibly well. Listening to stuff like In the Ghetto and Jailhouse Rock, you know why the guy is THE king of Rock and Roll! Really, Elvis probably had the best voice of all time, and pretty much could sing anything. Almost no one is in his class.
Out of these...tough to choose really. I'll say Queen, since they were the first rock band I really listened to and loved right away...the band that got me into rock in the first place, as I DO hate 99% of music on the market today. lol
