Feature description

Set a cache limit when the option to download the songs when finished playing is activated.

Then you could set a limit of only 1GB for the app to use. It would be even cooler if it deleted older songs when adding new ones, but it would be nice if that was a disableable option as well.

Why do you want this feature?

I would like this feature because it would prevent my memory from filling up and filling up uncontrollably and having to go to the app's storage to see how much space it is taking up.
