A listener likes the track they are listening to so they either add +1 to the like count by hitting a button, or they “kind of” like the track, so they rate it 3 stars out of 5.
Personal Feedback:
Personally, I like the star rating option, but either would suffice. If the like option is selected, there should not be a dislike option.
It would be ideal if you gave the widget owner the ability to choose which option they prefer.
The like count or average rating should be shown to the listener.
