yeah, i don't technically own it either i never got around to buying ultra or exciter, so i downloaded them.Ah, I don't have that one, so that explains it.
I've never heard Martin's solo stuff, but I've heard a lot of the tracks off Dave's second, Hourglass. It's pretty good, in my opinion.
martin's stuff is okay, it's different than depeche mode. i've heard hourglass is good, but i've never gotten around to buying it or at least downloading it.
