I tended to see the 90s as a rather boring period - not much new, mostly 80s trends continuing. However, all the posters here have reminded me that a number of really great songs came out in that decade.

Local heroes-
Political anthem
*) Don't have them on CD, for good reason, but they are nevertheless quite typical for certain periods of the 90s.
