Well, I have this Buzz Ballads collection that fits your bill. Has Glycerin on it. A couple of upbeat shit tracks on there but a lot of nice depressed stuff. All pop hits, though, if that doesn't bother you. Got cool depressed stuff like Doll Parts, Hemmorhage In My Hands, lots of sweet stuff.... Probably exactly what you want since you like Glycerin.
Buzz Ballads - 2 discs. Not all the tracks are killer but most of them are. A lot of bands have one or two of these slow, sad songs, but the great thing about this comp is that it puts a bunch of those together, so it's not one depressed song with a bunch of upbeat songs, it's all (well, mostly) depressed songs.
That's probably a lot more what you're looking for than the real grunge. Wish I knew where more of that depressed kind of stuff was located but that's about all I've got for it. You could also try those depressed singer-songwriters like Leonard Cohen, Elliot Smith, and Nick Drake. That might be what you want. But stay away from Sufjan Stevens htat guy is upbeat as hell. ...if Hell was upbeat.
Also maybe The Verve. I don't like them but they have that hit Bittersweet Symphony and it's name sounds pretty depressed, so... Don't really remember the song but they're that kind of thing. And I guess maybe Blind Melon. I don't listen to them either but I think that's their style. And go for some Jeff Buckley, he kicks 10 asses a minute. Check out tracks by hime like Hallelujah, Mojo Pin, Dream Brother.
One last rec:: There's also
Negative Saints Down. He's pretty talented and I consider that stuff to be ridiculously depressing.
Oh, and another important thought. What about the unplugged albums by grunge bands? Maybe not quite as electric as you'd want, but if no others then at least Nirvana's Unplugged is intensely depressed, slow, ploding, and awesome. And it has Come As You Are and Polly. So definetly up your alley. Also I'd reccomend Alice In Chains's Unplugged. It's composed almost exclusively of their depressed and slow, plodding songs. I don't think Stone Temple Pilots has one but if they do then that would be a good thing to consider because they have a lot of upbeat songs but they also have a lot of great depressed songs like Creep.
