I listen to a very popular radio station from Germany in the work a lot and it's shocking how often they play 7. Like it plays at least 4 times during the week and on one day they even overdone themself by playing 7 a total of 5 times in 4 hours. The radio station a grocery store in my city plays is also freaky cause I was in there for 30 minutes and they played Cupid 3 times while I was in there. Another radio station my last workplace had, that was specificaly made for the store, so customers would be blasted with ads after all 2 songs about stuff that was on sale or services the store provided, they also overdone it by playing Permitions to dance at least 2 times every day.
that's shockingly much. Also funny.
