I have posted this Issue before but It vanished for some reason...
In you Daily Mix, the list just randomly displays a song as liked or not liked no matter if you actually clicked on the heart before or not.
Most of the time the hearts in the list view don't show the correct state while the heart in the bottom left does. I did see it happen the other way around but do not have a screenshot of it (yet).
In this case the song "Dream Sipping" has a heart next to it eventhough I have not added it to my favorites:
Now the next Song in the List (Pretty Things) has the exact opposite happen to it (appears not liked in list but actually liked wich is correctly shown on the bottom left):
But for some songs everything works fine:
Here I have marked all songs that are not displayed correctly (it appears to be random):
When you actually click on the heart for a song that isn't displayed correctly spotify does the action you would expect: For songs that appear as liked it 'removes' them from your favorites even if they never where in your favorites in the first place. For songs that appear as not liked but are actually liked it moves them to the top of your favorites as if you just added them.
I can reproduce this bug about 50% of the time by doing this:
-Go into a Daily mix
-play a song from the list
-play a song from the bottom four or five songs (were the songs fade away)
-repeat last step until Spotify does some wacky scrolling and everything becoming jumbled up.
We haven't heard from you in a while!
