M.I.A., and then relax

I decided to have ataste of what the young ones are listening to, and shopped M.I.A.s "Kala". Apart from some vocoder (or hose singing) and smurf sounds, this is a pretty cool album! How do yo classify this then, is it rap, hip-hop, pop - and does it matter?
I realise that it may not always be smart to follow my recommendations, since one day I shout for joy over something similar to noise, and the next praise some reggae or country and western. To day I present a list of Norwegian artists guaranteed NOT to scare the shit out of you: Solveig Slettahjell, Tord Gustavsen, Silje Nergaard, Susanna and The Magical Orchestra, Jan Garbarek, Kobert,Hanne Hukkelberg, Arve Henriksen and Kristin Asbjørnsen. Relax!
