I'm 18 and I listen to music from almost all eras, 1960's to the present. My interest in music only began 2 years ago strangely and started back in the 60's and 70's. It was like a floodgate opened and I truly began to understand music.
To name a few.....
1960's- Simon Garfunkel, Early Pink Floyd, the Beatles, the Who, Yes, Fleetwood Mac
1970's- Pink Floyd in their Prime, Led Zeppelin, Rush
1980's- Boston, REM, U2, Pink Floyd in decline, Red Hot Chili Peppers
1990's- Pearl Jam, Goo Goo Dolls, U2, Nirvana, Smashing Pumpkins, Green Day, Fuel, Massive Attack, Foo Fighters, Oasis, Live
2000's- Explosions in the Sky, Staind, Snow Patrol, Linkin Park, Coldplay, Three Days Grace, Green Day, The Fray, Train(Only their early work)
I'm unsure right now whether I like Creed.
There is a lot of good music out there that people just don't seem to know about.
