Spotify is an online streaming service that includes popular, classical and jazz recordings, along with podcasts and comedy recordings. Users can access Spotify via their web browser (aka the Web Player) or through the mobile app.
Spotify accounts are free, but include ads both on screen and played in between tracks. One can listen commercial-free if they pay for a premium subscription.
Note: You can only save one track at a time to a playlist. If there were several tracks on an album that you wish to add to a playlist, you may want to add the whole album to the playlist, and then go to the playlist to individually delete unwanted tracks.
