I have and have liked too much music to list it all. A lot of what I have is on vinyl and boxed up since I haven't had a working turntable in a long time. There are some things I didn't even remember I had (like Van Der Graaf Generator) until I started poking around on some review sites. Anyway, here is some of what I like, but it's nowhere close to everything. Oh yeah, besides what I list below, I like Arena too.

My favorite bands/performers ever: (
some of my favorites of their albums in parens)
Genesis (Nursery Cryme, Foxtrot, Selling England by the Pound) – Still loved em with Phil until he caught the pop bug, but the Peter era is my favorite.
Peter Gabriel (3rd and 4th albums flawless IMO) - included in Genesis, but his first 4 solos are so good and so different from Genesis that he needs his own mention here
R.E.M. (Murmur, Reckoning, Fables of the Reconstruction, Automatic for the People)
Sugar/Bob Mould (every last scrap of it – maybe Copper Blue if I were to pick one album)
More music I like a whole lot (again no particular order and not a complete list of their good albums):
IQ (Tales from the Lush Attic, The Wake) - probably belong on the list above, but I won't move them there until I complete my collection
Neil Young (Everybody Knows This is Nowhere, Mirror Ball)
Jethro Tull (Thick as a Brick, Songs from the Wood, Aqualung, Minstrel in the Gallery, Bursting Out - my favorite live album by anyone)
Pearl Jam (Ten, vs.)
Talking Heads (More Songs About Building and Food, Remain in Light)
Weezer ("the blue album," "the green album")
The Replacements (Tim)
Kansas (Leftoverture, Point of Know Return) - my first favorite band once I started buying my own music, don't listen to them so much anymore, but they still deserve mention
Soul Asylum (Hang Time, Grave Dancers Union)
Pink Floyd (Wish You Were Here, The Wall)
The Who (Quadrophenia, Who's Next)
The Rolling Stones (Some Girls, Exile on Main St.)
Led Zeppelin (Houses of the Holy, 4th album – really could pick any of them)
Belly (King)
Buffalo Tom (Big Red Letter Day)
Pixies (Doolittle)
Hole (Live Through This, Celebrity Skin)
Nirvana (Nevermind, In Utero)
Lacuna Coil (don't own any of their albums yet but will probably have them all pretty soon)
Cowboy Junkies (Black Eyed Man)
Muddy Waters (Hard Again, but really anything he did)
The Afghan Whigs (Gentlemen)
Gentle Giant (Freehand, In a Glass House)
Marillion (Script for a Jester's Tear, Fugazi)
Yes (Close to the Edge, Going for the One)
Supertramp (Crime of the Century) – perhaps the worst name for a band ever, maybe it was a joke?
Hot Tuna (First Pull Up, Then Pull Down; Burgers)
Soundgarden (Superunknown)
Alice in Chains (Dirt)
Frank Zappa (Apostrophe)
Grateful Dead (Working Man's Dead, American Beauty)
The Band (The Last Waltz)
UK (UK)
Roxy Music (Siren, Avalon)
801 (801 Live)
Twelfth Night (Live and Let Live)
Lately I'm also liking the "symphonic black" bands although I haven't bought any albums yet. I particularly like the ones with angelic female vocals. Male vocals are fine too, as long as they don't grunt.

I'll probably add more to the list later as I think of it, but the above should be enough to start talking about.
