My childhood basically consisted of 1950s doo-wop, motown & harmonic groups of the 1960s, disco, and 80s pop music.
Some tunes that make me ridiculously happy because I was a really cool kid and had a nice time with my records, cassettes, and radio:
The Crew Cuts - "Sh-Boom"
Little Anthony & the Imperials - "Shimmy Shimmy Ko-Ko Bop"
The Mamas & The Papas - "California Dreamin'"
I played the everloving life out of this 45. (My parents probably still hate me for it.)
Silver - "Wham Bam Shang-A-Lang"
And a few 80s pop tunes that I was obsessed with:
[more in the undercut]
I still love grooving on this first track (especially when I'm drunk) because it's so full of happy memories. It's such a dumb song.
Kajagoogoo - "Too Shy"
Some years later, I started getting into some harder rock (thanks, Dad) and 80s hair metal, as well as 70s jazz/rock and powerpop; many, many years after that I started into my obsession with psychedelic rock, synthpop/electronic music from the 70s & 80s, 60s girl groups... the list goes on and on, and I could have written for HOURS about all the songs I loved as a kid, but I think this has been adequate.
