Pretty much any song that is played on the radio, I have no idea how the radio works in other countries but in the UK they play 10 or so songs about 30 times a day for about 2 weeks ....
Good fucking god!
They do it like this, each song is A, B, C, D, E, F, G, H, I, J. They will play them till a new song comes out by lady gaga, Rihanna or some other pop star then you will have B, C, D, E, F, G, H, I, J, K ... till a new song is released and then it goes C, D, E, F, G, H, I, J, K, L and I think you see the pattern emerging!
To add to the torment, the songs are very repetitive! The beat almost never changes, the chorus is the same 2 phrases repeated 4 or 5 times and there are 4 or 5 choruses per song! Just look at this
Imagine that 10 times a day .... It is akin to torture!
