According to former RRR announcer Cousin Creep (since working on US radio), the latest thing in radio formats in the US is
a format called "Jack". The Jack format appears to consist of the equivalent of an iPod full of songs from various incompatible genres put on shuffle, with prerecorded "short patronizing voice overs with lame postmodern attitude" between the tracks (whatever that means); apparently it appeals to the ever-shortening attention spans of the public or somesuch, and also means that stations don't have to employ DJs.
Could the radio format which only plays "the best 30 seconds" of each song be far off?
