Yea, that's a tough one. I have been stripping songs off of albums and making compilations since I was a kid with one of those cassette players with one speaker and the buttons all on one end...anybody remember those? The 1970s called and it wants its technology back!
For me, it has to be an album that you can listen all the way through and absolutely dig it all. Sooo many albums and I know I'm not remembering many that are very listenable all the way through, but one album always comes to mind: Bob Marley Exodus
I'm a hard rock guy, but there is a special place in my soul for Marley...and real roots reggae. Not the Pop stuff. Exodus is a cassette tape I bought, actually in Kingston Jamaica, where Marley is from. I bought it in a smelly, sketchy, Rasta run shop in the middle of town. Was there for business, not vacation; our ship lost an engine and we had to wait, docked in the port for the part to arrive. We had time on our hands...in Jamaica!
During a stressful period later in my life, I went back to that tape over and over after getting home from work, having a drink and a smoke. When I pressed play, I would be so uptight from life and spitting nails. By the end of the last song "One Love/People Get Ready" my stress was nearly gone.
