This is so true. It also happened in our office. When you listen all day every day, you really can notice those "fingernail" songs. Unfortunately, for us, what hurt Sunny was that all those fingernail songs were distractions and ended up irritating people instead... "I Will Survive," "Respect," "Knock On Wood," "It's Raining Men." So, off went the radio and we found a Soft AC station on the internet which everyone likes.
The funny thing is that the internet station seems rather heavy on Barry Manilow and, although a lot of people don't like his music and find it boring, it doesn't have that same irritant factor as those disco songs on Sunny have. So it might be worth noting that the texture of the music also plays a part in determining whether a listener will tolerate the songs he or she doesn't like. (Whereas that Gloria Gaynor song might cause someone to throw the radio across the room, Barry Manilow would just lull them to sleep instead... well, on second thought, maybe Barry would also cause someone to throw the radio). But the point is that different types of music affect a listener's tolerance level before that listener turns off the station for good. In this case, Barry Manilow is not as "abrasive" as '70s disco music.
