How can I enjoy music again?

I love classic rock, old heavy metal, a little bit of alt. rock, folk music, classical film scores, some dream pop, and occasionally blues music. My favorite artists are The Beatles, The Rolling Stones, The Who, Led Zeppelin, Black Sabbath, Deep Purple, Rainbow, Blue Oyster Cult, Queen, Aerosmith, Uriah Heep, Montrose, Ted Nugent , Van Halen, Pink Floyd, Jethro Tully, Kansas, Styx, Rush, Electric Light Orchestra, Jimi Hendrix, Eric Clapton, Cream, Creedence Clearwater Revival, Stevie Ray Vaughan, Santana, The Doors, The Kinks, Bob Dylan, The Byrds, The Velvet Underground, Simon & Garfunkel, Fleetwood Mac, Tom Petty, John Lennon, The Bangles, Metallica, Megadeth, Judas Priest, Iron Maiden, Foo Fighters, Matchbox 20, Brandi Carlisle, Mozart, Beethoven, John Williams, Mississippi John Hurt, M83, and Sigur Ros. The Beatles are my most favorite. I want to still enjoy these artists but I want to find at least a few others that I like. I know it's quality over quantity. I don't expect to like hundreds of artists. I'm also in a slump and don't have a social life? What do I do?
