I haven't popped into this forum for a while so missed the rundown - which was quite quick!
Here's my favourites from your list...
#30 Sweet. I had them on my list too. Love is Like Oxygen is my favourite too.
#29 Depeche Mode. An act in my Top 10
#27 Pet Shop Boys
#18 REM. Some great songs especially in early 90s. Losing My Religion is my fave.
#9 Elvis. Higher on Benny's list than mine
#7 Michael Jackson. In my Top 10 too.
#5 Elton John.
#4 Fleetwood mac. #2 on my list. Benny and I have very similiar tastes regarding FM songs
#3 Bee Gees. Another one that made my Top 10.
#2 Madonna. Yup, another act in my Top 10.
. My #1 too
I'm not the biggest fan of The Winner takes it All but SOS, Knowing Me Knowing You, Money Money Money and Dancing Queen are all outstanding.
