Remember back when Web Watch told you about how THERE SHE GOES by SIXPENCE NONE THE RICHER was called THE MOST PERFECT SONG EVER RECORDED? It was called that, in part due to its ideal song length, and for other reasons as well.
While it may not be a way to tell if what you’re listening to is THE perfect song or not, if you’re a LAST.FM user than we can at least identify if the key of your favorite songs all fall into the same ballpark or not.
In other words, do you favor listening to songs that are in the same key or not?
