"Hi Andrew, the feed shows your top 5 artists from the prior week. It's based on the information on this page from Last.fm...
http://www.last.fm/user/schweg...
As you can see, you only listened to 2 artists last week. When I made the feed, I decided that if a person listened to less than 5 artists for the week, that I would skip the update that week (ie. does a top 5 list make sense when you only listened to 2 artists). In order for the feed to update for you next week, make sure you listen to more than 5 artists this week." - Joe Lazarus
