Me, I have several favorite songs:
Dynamite, Taio Cruz
Just Wanna Dance
Twist My Hips
Reply if you have a favorite singer or song or at least enjoy all kinds of music!

Only Eric Clapton. Ever.

Currently Imelda May ... rockabilly, blues, jazz ... singer from Dublin.

David Phelps. I love/despise the man. He's the only tenor on Earth who can out-tenor me. Take a few minutes to listen:

David is the curly haired guy.

Too many to narrow down--some classical, pop, country, classic rock, New Age... and a bunch of others I don't know the genre for.

Favourite singer ever? Matti Salminen... Have a listen

I don't really have one single favorite. But...as far as voices go, I compare everyone the Michael Crawford's Phantom. And I'm a sucker for baritones.

Leonard Cohen, Always and Forever

Oh boy, like so many others, too many to recount. I love Judy Garland, though, and I think Barbra Streisand is a singer people will listen to hundreds of years from now.

Never Shout Never is my favorite singer currently.

I also really like Secondhand Serenade.

Also Basshunter, rounding out the top 3.

Utada, BoA, Kesha, Lenka, and Five For Fighting all make it fairly high on my list as well.

I like waaay too many. And then there are so many singers whose songs I enjoy, but would never list as a favorite singer, which I don't have. Some singers high on my list would be Adele, Bryan Adams, Kelly Clarkson (not a word, please! ), Colm Wilkinson, Patti LuPone, Shane Filan, and more.

Easy one: I am my favorite singer. I must be, I listen to me all the time. LOL

I'm currently listening to as much Christine Perfect as I can. Was she the best electric blues singer/songwriter ever? She may be better known to most as Christine McVie of Fleetwood Mac. Shopping for CDs of Chicken Shack (her first sucessful band) leads to some expensive items. I may have to go MP3 for those albums. Are they worth it? Right now I've got "The Complete Blue Horizon Sessions" playing. It was from the 60s and pre-echoes(?) some of her more famous Fleetwood Mac creations.

Billie Holiday. Patsy Cline. If we're just talking singing.

Karen Carpenter would have to be very high on the list of females; for males, it is a bit tougher, but how about Meatloaf!

Current favorite singers, male & female: Jack White & Caitlin Rose.

Male-Tomas Ledin. I have the greatest love for him!
Female-Agnetha Faltskog.

Beautiful barefoot babe, the incredibly soulful Joss Stone.

Shreyaa Ghosal!

Always and forever the best of the troubadors Jackson Browne

Michael Jackson.

I've stuck with him through thick and thin for 27 years through everything, since I was 11 and I'm now 38. I miss him terribly.

There's also David Bowie, Cher, Adam Lambert, Billie Holliday, Frank Sinatra, Madonna, Conchita Wurst...and the list goes on with a bunch of various artists.

Robert Zimmerman

Bob Dylan

Sadly, being of advanced years, most of my favourite singers are dead, and many unknown to those under 50 years of age, however:-

Female:- Ottilie Patterson, Nana Mouskouri, Judy Durham

Male:- Lonnie Donegan, Johnny Horton, Hank Snow

My favorite singers are Paul McCartney and Phil Collins.
