A perfect song? What are your choices?

Several have said the "perfect song" is one you never get tired of hearing

Mine:  

Spanish Moon--Little Feat

Asking Around For You--Joe Bonamassa

That's How Much I Feel:  Ambrosia  What?  How the Heck did this sneak in here?

Going to California--Zeppelin

Old Love--Clapton 

Once and Future Carpenter--Avett Brothers

Four Strong Winds--Neil Young

That's How i Got to Memphis--Tom T. Hall

I Was Young When I Left Home--Marcus Mumford's version

Free (Including violin intro)  Zac Brown Band

@nkphoto --While I don't listen to a lot of jazz apart from Art Tatum, thanks for pointing us to this piece--I first heard it when i bought a trumpet for my son and a Sketches of Spain CD came with it, but after listening to this version i prefer it over Miles' version.  Truly beautiful and Chet Baker's solo is sublime...
