I'm totally out of my depth here, but I'd say put on some Siouxsie (showing my age here, I know).

Bauhaus, Velvet Underground, Berlin-era Bowie, Sisters of Mercy....

Modern Lovers "Pablo Picasso", Smiths, Cure, Depeche Mode....

Paging kellydamnit!

I'm probably a bit too old school for this but I'll throw a few ideas out there. Jesus Built My Hodrod should be in everyones record collection. Killing Joke have a lot of tracks that would fit the bill. The Sisters of Mercy's Vision Thing album had a big effect on me when it came out. This is probably the wrong type of music but I always think of Beaster by Sugar as being a great teenage angst album. Therapy were always great at teen-angst too, check out Troublegum. Sheep on Drugs is probably too obscure. A Forest by The Cure is essential stuff. The Cramps are probably too far out. Depeche Mode. Laibach. Nine Inch Nails. Foetus. Front 242.

Of the more recent stuff I've liked I'd say Rammsteins Mutter album is fantastic, and World Coming Down by Type-O Negative is great too (although the more recent Life Is Killing Me is faster and punkier - although that's relatively speaking).

Oh man, what about Filter? The Swans? And what about that band you went to see last night, Circle Beats the Square, or whatever they were called? Oh, and definitely pump the Roxy Music. No Goth kid can be without the croon of Bryan Ferry.

Woah... I've been paged!

I'd go for something off the Sisters' Floodland before Vision thing, but that may just be my own personal preference. (also, unrelated, but I got tickets to see them next month for Valentines day! eeee!)

If you want more recent stuff go for songs by:
VNV Nation, Apoptygma Berzerk, Assemblage 23, Wolfsheim, Stromkern, and Covenant.
(There's more I could list, but those are the bands that every goth/inustrial club in North America, maybe the world, will play at least once a night, without fail, again and again.)

I'm also a BIG fan of Joy Division, KMFDM, Front 242, Skinny Puppy and the like. But, not quite so recent.

Try entering some of the suggestions into Pandora.com.

I was more on the punk side of things, so.. The things that saved me were: Fugazi's 13 Songs or Repeater (esp. Merchandise), Kerosene by Big Black, OpIvy, Ministry's In Case You Didn't Feel Like Showing up,( & totally agree w/ Dodgy's Jesus Built my Hotrod mention), the first 3 Primus albums, the first NIN album.

And it's nowhere near goth, but: the entire Jawbreaker discography.

Oh man, I'm old. Almost all of that music predates the first Clinton administration.

Oh yeah, Jesus Built My Hotrod. Yeah.

Great suggestions, thanks!

The list so far:

1) Skinny Puppy
2) Dismantled
3) The Swans
4) Joy Division
5) Depeche Mode
6) Stromkern
7) Sisters of Mercy
8) Siouxsie and the Banshees
9) Ministry
10) Laibach
11) C17H9NO3 or Tertium Non Data
12) Fields of the Nephilim
13) Clan of Xymox
14) black tape for a blue girl
15) Xmal Deutschland
16) Switchblade Symphony
17) Rasputina
18) Wumpscut
19) Covenant
20) Wolfsheim

And just fer kicks I'll broadcast it on mecharadio one of these nights.

Well, the Bauhaus cover of "Ziggy Stardust" clearly needs to be on that list.

As does Jesus and Mary Chain's "Happy When it Rains."

And, as much as it pains and embarrasses me to admit it, at least one Smiths song couldn't hurt.

What about some nice pouty Echo and the Bunnymen? Maybe Killing Moon?

The Revolting Cocks' 'Beers, Steers and Queers'?

Peter Murphy - "Cuts you up"

If you're looking for industrial, I cannot help but think that earlier Nine Inch Nails (Head Like a Hole) would be worth a song or two. Also, I loved Front 242 as well, for an idea.
