What does it mean when a Guy plays a song for you in a group setting?

we have a small friend group and we meet up once or twice a week to hang out and i do find him attractive but have yet told him. Well recently he played a song for me to listen to and it was a love song and i noticed he never did that with anyone else in the group before.

The song he played was a song he wrote personally himself. So this is why I thought to ask. Danke.
