This is purely my guesses for popularity, not my personal tastes necessarily...
1) Smells Like Teen Spirit - I'll have to say that song is what changed popular music in the early 90's, making all the hair band glam rockers rethink their game or take up painting houses for a living.
2) November Rain - Huge song at the time, and is still played fairly often today on popular rock stations.
3) I Will Always Love You - That godaweful Whitney Houston tune was in major play in the 90's. Still makes me cringe today.
4) Enter Sandman - I remember this was very huge when it came out, and seemed to turn Metallica into a mainstream pop/metal act.
5) My Heart Will Go On - Celine Dion should be shot dead. My god, what an overplayed, over-rated song.
I can't think of more now, but those 5 seemed to get the most airplay in the 90's. Some are really the worst songs ever made in my opinion ( minus Nirvana ), but there you go.
