Go listen to some metal. Preferably something along the lines of Children of Bodom, or Judas Priest.

Them Dancing Days
First Aid Kit
Daughter
Beck
Arctic Monkeys
Brendan Benson
Raconteurs
Matt Corby
Jonathan Wilson
Jackie Greene

For the Foxes are pretty good, especially their song 'Moonlight Ride'

If you like Ed Sheeran, you'll love anything by Ben Howard, he's another British singer/songwriter.
I recommend 'Only Love' and 'Keep your head up'

Also Fun. Are a good band, with more acoustic songs

Maroon 5 are great too.

Hope I've helped you a little: P
