Typo in songtitle

Hey, I was hoping one of the mods could fix this issue with the Finntroll song “Människopesten”.

I added it to last night's setlist (http://www.setlist.fm/stats/songs/finntroll-3bd6f858.html?song=M%C3%A4nniskopesten)

…but I noticed it is generally misspelled in the database as “Manniskopesten” (with an “a” instead of an “ä”)

Could some kind mod please take a look at that? Thanks!
