I like Lady Gaga - she's quite good for the kind of stuff she does - she has a good voice. Also, I like some of Kyle's songs - Obviously 'can't get you outta my head' is annoyingly catchy, but I think 'Confide in me' and 'Where the wild roses grow' which she did with Nick Cave are actually good.
I don't mind some of Lana del Rey's songs, they can be quite interesting. I also like Joy Division, New Order and Depeche Mode.
Probably the only 'guilty pleasures' are S club 7, as I liked them when I was little
