There are some, when i had enough and just want to be on my own, then its clearly "Tierd of waiting" by 2PM.
When i´m mad then its: "She´s Gone" by G-Dragon or "We all go down as one" by Bosshouse. I really wish for a barfight then XD
And if i´m more in a Sad mood than its "Holiday" from the BeeGees (and if i need something to laugh than its something from the Trackshittaz. Right now its "Woki mit deim Popo")
