I mainly heard Laser while out and about rather than listening on my own radio as I found it extremely repetitive after the first few weeks. Whenever I did hear it there were certainly some songs that were on very high rotation, several times a day. Ones that come to mind are Queen - Radio Ga ga, Art company - Susanna, Tears for fears - Everybody want's to rule the world, Opus - Live is life.
I tended to listen more to Radio Monique and in the early evening to Jamming 963 after Monique had finished and before the so called god squad stuff.
