British charts, 0th birthday: "Chirpy Chirpy Cheep Cheep" by Middle of The Road. Interesting...I just rediscovered this song a year or two ago, courtesy of I'm Sorry I Haven't A Clue--it sounded instantly familiar, and I was compelled to buy it on iTunes out of sheer nostalgia.
American charts, 0th birthday: "It's Too Late" by Carole King. I'm fond of the "Tapestry" album, but this song was never a standout for me.
British charts, 12th birthday: "Baby Jane" by Rod Stewart. I don't think that I've even heard this one, but maybe I have. At this point I was probably still avoiding Rod Stewart because I hated his voice.
American charts, 12th birthday: "Every Breath You Take" by The Police. This one I definitely recall, which probably isn't that surprising. My brother was a bit fan of The Police, so I heard a fair bit of them.
British charts, 14th birthday: "Frankie" by Sister Sledge. Wow. If possible, I think it's even less likely I heard this one than the Rod Stewart one.
American charts, 14th birthday: "A View To A Kill" by Duran Duran. Ah, yes, definitely. I first started getting into music in a big way in the summer of 1984, mostly via Duran Duran, so this was the first new track of theirs to come out after that time. Just as the band was fragmenting, so this might even be their jump-the-shark moment.
British charts, 16th birthday: "It's A Sin" by Pet Shop Boys. A big hit of my MuchMusic video-watching years, definitely quite familar, though never quite my favourite either.
American charts, 16th birthday: "Alone" by Heart. This song is always tied, in my mind, to my high school crush...not to mention my crush on Nancy Wilson. So, you know, memories, nostalgia...
British charts, 18th birthday: "Back To Life" by Soul II Soul. I was without cable for a year or two when I was at university, so I have a bit of a gap in my musical awareness, but this was one of the songs I recall from that period. My friend/roommate Jeremy wasn't that fond of it, though.
American charts, 18th birthday: "Good Thing" by Fine Young Cannibals. Also not my favourite track of theirs, but I certainly remember it quite well.
British charts, 21st birthday: "Ain't No Doubt" by Jimmy Nail. I definitely remember this song, though it was years before I got my own copy of it. I mostly remember Jimmy Nail for singing "Love Don't Live Here Anymore" (I still think of it as principally a Madonna song, though).
American charts, 21st birthday: "Baby Got Back" by Sir Mix-A-Lot. I never got that heavily into rap music, and certainly by this time I was actively avoiding it as much as possible. I don't know if I've ever heard the original of this one, though the Jonathan Coulton cover version is perfectly fine.
Yeah, ages 14-17 were my main immersion in mainstream pop music, as you might be able to tell. Now it's rare for me to hear a song the year it's released. I try not to stay stuck in the past, but I don't shun the music of my childhood either...
