It's a brilliant exercise in debauchery. Love it live, love it on the album. Yes it's experimental but yet it remains catchy as hell, not an easy thing to accomplish when you're breaking moulds - that'll be a great melody then. Despite the bells and whistles, like the rest of the album, it sounds organic, gritty, spontaneous and delightfully filthy. Up there with the best postcards Bono's ever sent.
