They've got their own festival in Örebro this June as part of their 20 year anniversary, so maybe it's something tied to that. Could be another one of their Millencolin Invitational skateboardings contests too.
Awesome news! The first two songs seem to be new, because i have never heard of them anywhere before. It will also be nice getting a non vinyl version of "junkie for success." The rest have all been released on various singles and imports.
