No full-length yet, eh? I find this shift very interesting. This is one of the, if not the first time in the digital era of music (starting with cd's) that new popular genre managed to retain its own preferred way of releasing records. 45s became records, live jams became concept records and hardcore bands go for full-lengths, but the dance artists stick with the the single-centric angle. It's interesting, because other tropes like the 1+1 min intro/outros are on their way out already since they're redundant in the day of digital dj'ing.
