Unbeknown to be me, it looks like our dubstep and drum & bass only feeds had been broken for what was potentially quite a while. Well, good news – I fixed ‘em.
If you want the dnb only feed its here: http://feeds.feedburner.com/exbc-podcast-dnb and the dubstep only feed is http://feeds.feedburner.com/exbc-podcast-dubstep
Sorry for error folks.
