though it is now defunct, i have a new favorite label, comfort stand. they moved on to do other things as of 2006 but all of their albums are up for free online and through the archive. it’s mashup and electronica stuff and all that i’ve listened to so far has been quite good. i do recommend the following as a starting point.
Interplanetary Materials – this is what i started with. good music to work to.
Wakka Chikka Wakka Chikka – porn music for the masses. heh. wonderful.
take a listen, good stuff.
