Music is a very personal thing, but here are some slightly obscure songs that made a big impression on me:
Eddie Vedder. The Wolf. (Picture Eddie on a cliff out in the Dakotas somewhere howling into the moonlit valley below)

Quicksilver Messenger Service. Fresh Air. Hidden gem from 1970's San Francisco.

Neil Young. Powderfinger. Probably my fav. Neil Young songs. Love the guitar lead and the lyrics

Keb Mo'. Every Morning. Doesn't get much more soulful and authentic than this.

Paul Ray and the Cobras. Other Days (A young Stevie Ray Vaughn ripping it up on guitar)

Louie Armstrong. You go to my head. You will laugh, you will cry

Cream. Outside Woman Blues. Classic Eric Clapton 'Woman Tone'. Mind Melting

Metallica. No Remorse. First 45 seconds are pure lead guitar heaven. The rest is just so kick ass. Get's my heart pumping every time. Good while driving in your car at high speeds.
