This is a recent Spotify Pre-save campaign for Nashville artist Rachel Price.  You can check out the campaign at http://presave.tweematic.com/rachelprice

This is a good example of combining an incentive together with a Pre-save to Spotify campaign to increase the overall performance of the campaign by giving fans an additional incentive to connect with the artist!

Once fans pre-saved Rachel's upcoming album on Spotify, they were encouraged to share their presave on Facebook and Twitter. Our Presave Platform provides a number of flexible presave options including:

• Ability for users to create or select an existing playlist
• Ability to automatically create a playlist for the user
• Ability to have user follow an artist playlist rather than creating a new one
