i work on a music streaming app.

bug: playlist description shows there are X songs inside. But when you go inside it says there are Y songs in the list. the list actually containing Y songs.

hack: when a user goes in, cache Y and display it outside in the description next time.

result: user sees X songs in playlist description, goes in playlist and sees Y songs. goes back to check why it said X before but now it doesnt say X anymore coz we cached Y and display that in the description from now on so the user assumes they are imagining things
