I guess it would have to be L.A. Woman and Riders on the Storm by the Doors. Because I listened to them and related to their music when I was young. Jim Morrison knew how to get inside your head. Any time I hear either of those two songs, I think about when I was young and life was different.
All Along the Watchtower- Jimi Hendrix
House of the Rising Sun - Animals
California Dreamin' - The Mamas and the Papas
Paint it Black - The Rolling Stones
Why? Cos I grew up with this music, and I have fond memories of my mother.
