It's quite often some free concert in Kungsträdgården. On tuesdays during the summer the local radio station P5 use to have live broadcast with some current well known Swedish artist. Other radio stations also use to have big festivals with a lot of different artists, both local and international. And the best... everything is free.

Music in Kungsträdgården.
Favorite thing: You can find this at Kungstrådgarden. Most of the times you can only see kids are playing it but don't be ashamed to try it, we always have that child's part inside all of us right?! 50SEK for 5 mins.
Wander through the Kungstradgarden (formally part of the palace gardens).
Not that you can tell very easiliy, but this is me and my Swedish friend Lotta (Znaky on VT).
