A very broad question with a very broad answer. I'll get back to you when I have the energy and time!
Buck Owens,My Dad,Merle Haggard, Eric Clapton.
So many. Some I mentioned before. The Beatles, Joni Mitchell, Sarah McLachlin, Fiona Apple, Aimee Mann, The Ditty Bops, Tom Waits, Joanna Newsom. Many many more. Usually, these people all have one main thing in common: intense creativity, and a love of the absurd or profound. In many ways, I consider most of my idols to be musical prophets and lyric philosophers, and I strive to be that as well. I try to put meaning ahead of form, except when dreams and nonsense is churning in me. At which times, I put fun ahead of meaning.

I don't have a career per se. I've been inspired by tons of musicians - starting when I was a little boy and loved to listen to Jo Stafford sing on my father's records. Okay...The Beatles collectively and individually, Van Morrison, Stevie Wonder, Maxwell, Jill Scott, Norah Jones, India.Arie, Billie Holliday, Ella Fitzgerald, Jim Morrison, Jimi Hendrix, Janis Joplin, Lyle Lovett, Robert Goulet, Leonard Cohen, Bob Dylan, David Crosby, Stephen Stills, Graham Nash, Neil Young, Fred Hammond, Donnie McClurkin, Norman Hutchins, Shirley Caesar, Vickie Winans, CC Winans, Joan Baez, Phil Ochs, Pete Seeger, Arlo Guthrie, Woody Guthrie, and so many more that it'll take a long while to come up with.
Oh wow, uhm... To name a few, Green Day, Linkin Park, Pendulum, and Adam Lambert are a few large inspirations to me.
Sarah McLahlan, Norah Jones, Joss Stone, Kwon Ji Yong, The Corrs
Jazmin Levi, Mercedes Sosa, Lila Downs, Violeta Parra, Victor Jara, Eva Cassidy, Lasha, Aterciopelados, Musica andina peruana. Todos los huaynos ayacuchanos, carnavales, huaynos y muslizas, musica mexicana, huasteca. Trova, jazz, blues, new age, msucia de los adnes de toda america latina, musica,.. musica nueva y de otros paises del mundo
Christina Aguilera is one of them, but I also found inspiration in Nina Simone, Mariah Carry, Janis Joplin, and a bunch of other great musicians.
All the classical composers. And certain pianists, like Sviatoslav Richter, and Shura Cherkassky (who flutter pedals).
All music from the 12th Century deep into the 20th. Just about everyone well-known.
Pop music, too. Historical popular music (before the 20th century), and mostly American pop from that point, onward.
Swing made a big impression on me. So did Novelty Music. And the studio orchestra sounds that were popular throughout the 1950s up to about 1980.
All the usual vocalists.
I have a special love for Hungarian Gypsy music, the way Bartok did not like it!
I love Menken and Ashman. That team inspires me.
Anyways, it would be bob marley and the wailers, Buklod, Tenacious D and The beatles.
