hiding/unhiding user collection items from recommendation

[sabjorn]

one issue in the past has been when older tracks are influencing the recommendations. There is currently no way to control this. However, there are two potential options:

1. hiding/unhiding on Bandcamp could be the control

• this would require having a user's whole collection to be updated based on the current state
• this would only be run against users that are actively using the app

2. a settings page where users can select/unselect tracks

• this is probably the best option because it is more flexible and can also provide a listening experience for the collection
• when sorting is available -- users will be able to use the sort function on this list
• there should be batch process (enable/disable all) so that the whole thing is very easy to use an dynamic
• loading this page could force the cache to clear
  • also -- maybe diffs could be tracked (i.e. user has a new track or users' friends have a new track) and this could be used to clear cache as well (rather than just a set number of days)

#2 seems like the best.

note: it will be very important that even if tracks are not enabled they are still counted when filtering out so that users don't get recommended tracks they own
