Robyn, Avicii, more are getting their own Swedish postage stamps

Sending letters is about to get much more exciting: Max Martin, First Aid Kit, Robyn, Avicii, and Seinabo Sey will be the new faces of Sweden's stamps.

Sweden is one of the world's pop music capitals—according a press release, it's "third in world in pop music exports"—so it makes sense that the country would give some of their biggest stars their own stamps.

While all five acts hail from Sweden, they represent different kinds of pop music, ranging from Robyn's dance-pop to First Aid Kit's pretty folk. The stamps will be available in Sweden Jan. 15.
