Hearts on liked songs are nearly impossible to differentiate when High Contrast fonts are enabled for accessibility.
Without high contrast fonts enabled the heart fills in green.
When high contrast fonts are enabled the heart fills in with black.
When the heart is not enabled it's transparent, but since the background is a very dark shade of grade it is very hard to differentiate if the heart is filled in or not -- this is the exact opposite of accessibility & high contrast.
When high contrast fonts are enabled for accessibility it would be fine to fill the heart in green since that is a high contrast, rather than black on a dark background.
