I don't know about you, but I can't work without music at all. Youtube request for "quiet music" gives relax radio stations. Listening to those radios makes me fall asleep. I ruined my previous contest because of them :( 315 round is approaching, so I've managed to collect some best collections of calm music:

https://www.youtube.com/watch?v=07n4hliWkNs -- Pink Floyd

https://www.youtube.com/watch?v=oavMtUWDBTM& -- Russian classic (no lyrics)
