When I was a little kid, I had access to an old reel to reel tape deck. I loved to listen to that thing and when about 10 years old discovered 3 tapes that I fell in love with: Blind Faith (self titled); Beatles - Abby Road (side 2) to be exact; and Rolling Stones - Let It Bleed.
I'd put one of those tapes on, turn out the lights and head to bed with the most magical sounding music floating through my bedroom.
Tonight I had my phone on shuffle and Gimme' Shelter came on. It immediately transported me to my childhood bedroom. It was a great memory, but was dashed by the next song from Singing in the Rain - Make 'em Laugh. Damn shuffle.
