My music taste definitely goes in cycles. I find a couple of songs that I love and then just listen to them over and over again till I can basically sing them and cant listen to the tune anymore. At the moment I am making my way though the HBO series Girls Soundtrack which is filled with fun energetic music from new and upcoming bands. My favourite song from this album is I Love It (feat. Charlie XCX) by Icona Pop. Its so loud and completely electronic. PERFECT getting ready/ club song.

When I'm in not such a loud mood my turn to artist at the moment are Bastille and Benjamin Francis Leftwhich. (I know I'm late to the party!)
Pompeii is the best Bastille song in my opinion, and for BFL Atlas Hands or Pictures.
If you intrestd in new music from unknown artists iTunes has a free download every week which is normally really good
