Tina Cousins ?
Not really, although...
Nope, but that was one of my first results in my search, at first I was convinced that the title contained "Alone", although I couldn't find it searching for that.
Track name (or chorus) may contain, "Alone", "Heart", "Love" or similar. (I think)

YES! THANK YOU!

My clues weren't great but YES.
Nostalgia itch officially scratched!
Thanks everyone for your help.
