basically, it's a phrase used as an interjection when the radio station or club DJ is playing some
trash. The phrase is used frequently by Morrisey on the 1986 Smiths
hit "Panic" where he exhorts that the disco be burned down and the "blessed DJ" by hung up "because the
music that they constantly play / it says nothing to me about my life". Considering that's true today, it ain't such a bad idea at all.
