Those singers you enjoy,....that don't really have a great voice?

I have come very late in life to an appreciation of Agnetha Faltskog of ABBA.

Aside from being gorgeous, in her prime I think she had one of the finest voices in pop music.  Such bell-like purity of tone, incredible range without over singing, incredible versatility.  And of course when combined with Frida the famous ABBA “third voice” arose.  Both girls were talented singers to start out with but Benny and
Bjorn pushed them to their limits over and over until they became thoroughbreds in the pop singing world.  

I thought I'd revisit my guilty pleasures with how guilty they are 

Louis Armstrong  9 albums alone and duets & 5 album Autobiography 

Rod Stewart   2 Jeff Beck , 4 Faces , 5 Rod Stewart  - not including second copies

John Prine   9 on self and 3 in storage 

Billie Holiday  7 albums 

Bob Dylan   2 & 4 album biograph

Neil Young   1 C.S.N & Y  & 4 solo & 1 Stills Young  Band in storage

David Bromberg.  3 albums 

and I'll add Janis Joplin.  1 solo and 3 with Big Brother and the Holding Company

I am very guilty of having guilty pleasures .

Bob Dylan... but that depends on what you mean by "great voice" because it could be argued that his is the greatest of all.
