There is a stuga in the archipelago which has a specific place in pop history. It's on the island of Viggsjö, and it once was the summer home of Björn Ulvaeus. He spent his holidays there, often visited by his friend Benny Anderson.
If you haven't guessed already, Benny and Björn are the 'BB' in ABBA. They co-wrote many of ABBA's hits out on Viggsjö. I think it's quite a romantic image- the little cabin with a piano, a couple of friends, and long summer days spent making perfect pop music.
I really like ABBA. I'm not embarrassed to admit it.
