Good DJ, Dance, Mashup, electronica sites?

[cavalry]

Hey guys I have been trying to find some good dance, DJ, mashup, techno, electronica, etc sites. I've come across a few good ones like jetcomx, mashuptown, torrentech and beatportal but do you guys know of any other good ones?

Also any good magazines from the same genres I should check out? It seems that these type of sites are not as prominent as rock sites.

Thanks a lot!
