Because the app has never seen this track before, it would like to know Alice's mood before she plays it, so that it can understand if she might like to play it again if she's in a similar mood.

Alice can choose any of the moods (one only!) She can see what each mood icon means, because a notice pops up to tell her.
She chooses 'focussed'.
