4 - 2 points for a timeless classic (but I probably wouldn't play it at a wedding, because "not everyone will understand"; although it depends on the wedding and who's invited, of course)
5 - 3 points for the Irish tune, funny lyrics, and interesting vocals
7 - 1 point for the great Queen (although, in my opinion, it's not one of their best songs, even if it's somewhat thematically relevant)
8 - 1 point for the funny girls singing about Steve from Minecraft, probably
9 - 1 point for OneRepublic (a good song, even if it's getting a bit repetitive)
11 - 4 points for the cool ethnic music and interesting instruments
14 - 1 point for just a good song, slightly nostalgic
15 - 1 point, similarly)
To sell my soul
