Facebook will let friends learn about you by streaming clips of your favorite songs from your profile in a throwback to MySpace Music. You’ll be able to choose tracks to add to a revamped Music section of your profile that now actually plays songs instead of just showing what artists you Like, and you can pin your favorites right to the top of your profile. The feature will launch in select countries later this year.

While friends won’t be able to listen to the whole song to see how you express yourself, they’ll get to watch an accompanying video the collages artist photos and album art, like an algorithmic music video. Facebook could eventually strike streaming partnership with companies like Spotify or Apple Music to allow full-song streaming.
