You have two options when selecting the alarm music on your ROLL:
Choosing this option allows you to set the alarm music with the last song that was played from your phone or tablet. This can be music that is stored on the device itself or it can be music that was played from a music service (e.g. Spotify, Pandora, Deezer, etc). In the case of music services, you can select a specific song, a playlist or even a radio station.
Choosing this option allows you to set the alarm music with any song(s) from the local music library on your phone or tablet.
