It's Friday at work and I want to hear some new music.

So far I have tracks by:
Fucked Up
Lykke Li
Ponytail
Final Fantasy
Grinderman (remix)
Jay Reatard
Parenthetical Girls

As everyone seems to be chatting about them at the moment.

So, either recommend me the best songs by the bands above, or other new songs/bands I should check out plz.

Note: nothing boring. If you were ever into, say, The Koreans - you're disqualified because you can't tell what's good.
