I try to figure this whole genre business out because I think it would help me figure out the kind of bands I like. I was listening to Soundgarden's first album which is called "Grunge" but the floaty elements mixed with the groove oriented rock is what I came to associate with "Stoner Rock" Kyuss is reefered (pun) to as stoner rock. But they are heaiver/less melodic than lets say Monster Magnet. But the style reminds me of Doom metal... or what I thought was doom metal. The Obsessed I thought were stoner metal... but they are doom metal... The Melvins (Houdini era) is another grunge classic... which sounds like doom to me... but is often called "Sludge" Eyehategod sounds like doom with awful vocals, but is "Sludge" and My Dying Bride sounds goth to me... but is doom WHAT THE HELL?!?!?!?!??!
