I think you all pretty much summed this up. If it goes on the radio, it gets loads of airplay, on pretty much most stations. So wherever you go, it's being played. Of course, us Paramore fans don't mind this. But other people start hating the song, or loving it to the point where it's just annoying. So basically it gets overplayed. Like Weightless by All Time Low. I liked that song, but now I can't stand it becuase it's always being played on the radio, on tv, and people always sing it and quote the lyrics. So I guess people don't really like that to happen to one of their favourite bands songs. Hope that made sense...
