EP concerns

I've got a few new tracks that I'm thinking of releasing as an EP - I can't figure out if they work together though, if the track order works, or if they're consistent sounding. About half are faster paced/more electronic sounding and the other half are more instrumental-based/slower. Would it be better to split it into two EPs or put it out as one big one? Not that it matters a great deal, I'd just be interested to know. Here's a secret link anyway, cheers:
