I'll kick us off with an absolute banger...
Boyzone - Love Me For A Reason
I was like 6. I wanted it desperately. Listening back to it now, as a 36 year old man I can admit that it's an absolutely horrible bit of music....but it still takes me back to being a young kid.
The first record I chose was Ma Na Ma Na by the Muppets. The first record bought with my own money was Never for Ever by Kate Bush
Also, old.
