Favorite band or artist of all time?

1st of all Merry Christmas and Happy New Year to everyone at Audiogon!
I've Have been thinking about it(hundreds of choices)and lately  just wondering, If you had to pick just one, what would be your favorite band or artist of all time???
 Extremely hard decision!, but Mine would be Elton John.
(deeply rooted since I was 10 or 11) Old fart now😎
johnto. The Beatles definitely changed the landscape of Rock&Roll! Probably wouldn't have been the same without them. GENIUS 😎
Talk about Influenciaal!!!
So many great artists. Hard to pin down even the top ten, I do think that Chuck Berry deserves to be very high on the list. Mostly overlooked, for some unknown reason.

Impossible question, but it has to be Joni Mitchell. She got me through my teenage angst, just, with "Blue", my all time favourite LP and I'm 71 now. That's an awful lot of years.
For those folk who think Jimi Hendrix wasn't a good lyricist or a great guitar player or?..and his Strat didn't sound good! All I can say was he was a genius in all areas of music...period. IMHO...and apparently in most others as well!
