I don't quite understand this - the script doesn't return the top tracks of the artists I've tested with.
I've only used the regular button, not shuffle, and it is set to 5 tracks. I've also only tested with artists where I have all their tracks.
Then it should return the 5 top tracks, yes? No.
For Oasis, the top 5 tracks on Last.fm are:
2. Don't Look Back in Anger
3. Champagne Supernova
4. Live Forever
5. Some Might Say
The ones returned by the script were:
1. Stand By Me
2. Don't Go Away
4. Roll With It
The difference is quite striking!
