I am a big fan of music, and can appreciate most. (Not too much rap though)
I like a lot from the 70's, 80's (my high school years) brings back many memories and yes, many good songs.
I think the 90's took a dump though. Now, eehh. There are certainly the exceptions, but there is not too many out there right now of new bands or singers that impress me too much.
90's had too much grunge. Oh sure, Nirvana hit it big, but no one will ever convince me that they even had a fraction of talent of bands such as Fleetwood Mac, The Eagles etc.
