This should definitely show the name of the user and not "you":

The code for this card component is located here:
https://github.com/metabrainz/listenbrainz-server/blob/master/listenbrainz/webserver/static/js/src/listens/ListenCountCard.tsx#L15

This component needs to receive a required 'user' property expecting an object of type 
ListenBrainzUser which contains the name.

We also need to receive another prop 'isCurrentUser' like done here for example:
https://github.com/metabrainz/listenbrainz-server/blob/7855c8b58835551b8e6fa89e8f714d3b47914dc9/listenbrainz/webserver/static/js/src/pins/PinnedRecordingCard.tsx#L32
and used like so:
https://github.com/metabrainz/listenbrainz-server/blob/7855c8b58835551b8e6fa89e8f714d3b47914dc9/listenbrainz/webserver/static/js/src/pins/UserPins.tsx#L292

 
Then we can write "You have listened to…" when isCurrentUser is true, and "${user.name} has listened to…"
