I like a wide variety of music, I don't limit myself to just Elvis because I would ultimately dilute what effect he has on me. Variety is the spice of life. When I listen to a an Elvis record I haven't heard for some time it can spark a memory or reaction that ignites the passion I felt when I first became a fan.
My taste in music is so varied that it is hard to define a category e.g.
Clasical, Kiss, Aerosmith, Guns & Roses, Rolling Stones, The Beatles

U2, Led Zeppelin, Pink Floyd, Oasis, Blur, Queen, Tom Jones, Frank Sinatra, Dean Martin, Nat King Cole, The Ting Tings, Duffy, The Stereophonics, Killing Joke, Abba, B52's, Brian Adams, Cold Play, The Verve, Manic Street Preachers, Travis, The Silencers, Nirvana, Foo Fighters, Jamiroquai, The Police, Duran Duran, Talking Heads, The Smiths, David Bowie, The Stone Roses, The Clash, Madness, Richard Marx, Michael Jackson, Green Day, Beyoncé Knowles, The Killers, Snow Patrol, Maroon 5, Kings Of Leon
and so on.... I'm sure I could add at least another 50 to that list

however I always come back to Elvis
