This tool works out when the last time you listened to certain songs were. You can filter by only top artists, only top songs, or all songs. The week filter allows you to show only songs that were last listened to between the specified amount of weeks in the past. The tool works by compiling a list of all the songs you've listened to (by going through your previous weekly top played songs lists) and then ranks them by the last listened week.

Notes: Last played dates can only be kept as the week the song was played, because the Audioscrobbler API doesn't expose data about previous play times beyond the "most recent 10 tracks". Please also be aware that the greater "weeks ago from" you enter, the longer your query will take, as the Audioscrobbler API only allows one request per second. If the script is timing out, try reducing this value.
