If you open a track you already own, Fatstep turns the purchase into a **tip** instead of charging you twice.

## How tips work

Any amount you add on a track you already own goes straight to the artist as support. You are never charged again for music that is already in your Library, so it is safe to open something you own - you only pay if you choose to tip.
