Just added to the app is Katy Perry’s “Harleys in Hawaii” and “Darl+ing” from the K-Pop group Seventeen.

Both remixes can be downloaded on the GarageBand Sound Library. That also offers a number of free loops, sounds, and instruments to take the original tubes in different directions.

Using the Live Loops interface to remix, you can rearrange and and new elements while keeping the tempo and key in sync.

You can also head to any Apple Store worldwide and sign up for a new session where you can learn how to remix the Katy Perry hit with GarageBand.

GarageBand is for the iPhone and all iPad models. It’s a free download on the App Store now.
