For my years 7-10 any song off of the Beatles "Revolver" album, especially For No One, Eleanor Rigby, Here There and Everywhere, and Good Day Sunshine. My cousin who lived with us was 13 years older than me and for my 7th-9th birthdays he got me Meet the Beatles, Revolver, and Creedence Clearwater's Cosmo's Factory.
The CCR songs Lookin' Out My Backdoor and Have You Ever Seen the Rain, and Long As I Can See the Light, also bring me back to that time.
The melancholy of those songs bring me back to those times sitting in my bedroom and playing those songs over and over and even though I didn't understand the lyrics necessarily, I deeply understood the feeling in them. I suppose the reason they're still so powerful to me today is they were the only human communication to me at that age that was saying, "I know how you feel".
As far as upbeat songs from that time, the Beatles' I Want to Hold Your Hand and She Was Just Seventeen and CCR's Up Around the Bend. But they've kind of worn off. The melancholy ones still are incredibly powerful.
I was lucky enough to meet John Fogerty at a mall a couple of years ago and got to tell him how much his music meant to me. He was very nice.
