A perfect radio song is very subjective. In my opinion there wouldn't be many in that category from commercial radio and some people would say the same about the more alternative stations like Bitter FM. However, there would have to be times when a song comfortably fits in both camps.
I'm not sure if these songs were played on commercial radio but I expect they were. Anyway, they certainly found their way onto a lot of Bitter FM playlists and are worth celebrating for being the great radio songs they are.
Part 1, Middle Kids - Edge Of Town
This song "Edge Of Town" by Aussie band Middle Kids could possibly be the (quintessential) perfect pop radio song. It is a 'stop what you are doing and enjoy every second of it' song when it's heard on the radio. Hannah Joy's vocals are sensational and she takes it to a dazzling climax....... check it out and enjoy.
