When a person goes to look at an artist's albums, etc. there is a top songs area. Is this list based on popularity? best song? most purchased? what is based on? The thing that confuses me is when a new album comes out, a song off that album will go to the top of their top songs list. But down the road, it goes off the list and their old songs are back on top. It just disgruntles me because I usually purchase a song off the artist's new albums if they are in the top 5 and remain there. Yeah, call me obsessive and picky but I do it to control my budget and not waste money on an entire album where I might not like some songs and skip them all the time. How is the top songs worked?
