I have a great love for all kinds of music and don't limit myself to any one kind of music as you can see below.  Here I'll just list a few of the bands that I'm particularly interested in as of now (because the complete listing of all of the bands I like simply wouldn't fit!).

Marilyn Manson - Would probably have to be my favorite band as of now, believe it or not.  Don't like it?  That's okay, just don't send me any sugar coated hate mail and/or hate mail for it, please.  I can't wait for Mechanical Animals to come out!
Best songs:  Suicide Snowman, Negative 3, Misery Machine, Dope Hat, Get Your Gunn, Wrapped In Plastic, Lunchbox, Man That You Fear, Cryptorchid, Kinderfeld, Minute Of Decay.

Nine Inch Nails - When's the new album coming out, Trent?!  We've been waiting for four years now! ;-)
Best songs:  Something I Can Never Have, A Warm Place, Gave Up, Mr. Self Destruct, Ruiner, Hurt.

Switchblade Symphony - Some say they're gothic, some don't.  Well, I'll just venture so far as to say that they are.  Anyway, they have beautiful music to match frontwoman Tina Root's fantastic voice.
Best songs:  Clown, Dollhouse, Mine Eyes, Rampid, Soliders, Roller Coaster, Bad Trash, Sweet, Sleep, Sheep.

Radiohead - Need I really say more?  Completely brilliant band.
Best songs:  You, Lurgee, Airbag, Street Spirit [Fade Out], Black Star, Sulk, Just, Lucky.

Tori Amos - I saw her in concert last July, and it was one of the best concerts I've been to so far. Despite what many critics have to say, try out some of her work sometime.  It really speaks for itself.
Best songs:  Winter, Little Earthquakes, Silent All These Years, Precious Things, Pretty Good Year, Space Dog, Yes Anastasia, Marianne, Doughnut Song, Playboy Mommy, Pandora's Aquarium.

Rasputina - The Ladies Cello Society!  I discovered them about a year ago when I found out through the Internet that Marilyn Manson himself had remixed one of their songs called "Translyvanian Concubine", so I decided to check them out and was very impressed.  Very interesting lyrics and haunting, sometimes even a little bit (dare I say it?!) gothic melodies.  Pick up Transylvanian Regurgitations sometime and give 'em a whirl.
Best songs:  My Little Shirtwaist Fire, Transylvanian Concubine, Howard Hughes, Trust All-Stars, Rusty The Skatemaker, TrenchMouth, The Olde HeadBoard, Rose K., The New Zero, Leechwife, Watch TV.

Ben Folds Five - Ahhhh....who wouldn't love these nice young men with their unique, addictive sound?  A piano-based trio with very personal, thought-provoking lyrics that touch the heart and really speak to you....and sometimes even have you rolling on the floor laughing.  I hear there's even a BF5 cover band from Japan going by the name of Tom Collins Nine.  Interesting. ;-)
Best songs:  Mitchell Lane, Emaline, Boxing, Philosophy, Bad Idea, For Those Of Ya'll That Wear Fanny Packs, Best Imitation Of Myself, The Last Polka, One Angry Dwarf & 200 Solemn Faces, Evaporated, Steven's Last Night In Town.
