We've all suffered through "radio station hit music syndrome," which occurs when a radio station specializing in chart-toppers spends the entire day playing the same eight songs on loop. YouTube user "vissigan" noticed that such radio stations were not only playing the same set of songs, but that these songs were all exactly the same. 

The mashup above bears striking resemblence to DJ Earworm's United State of Pop mixes, but really drives home the point that nearly all hit songs nowadays sound eerily similar to one another.

Have music producers perfected some sort of eargasmic formula? Are we all turning into robots? Should we have listened to those kids in high school who wore black Metallica shirts and constantly warned of the ever-looming music-apocalpyse? Take a listen and decide for yourself.
