How to record mixes when using Spotify songs

Anyone know how to record mixes when using some Spotify songs in the mix?

Using DJ PRO and Reloop Mixon 4 controller- with Imac

Possible external recorder?

Thanks and Best

The spotify licence doesnt allow you to record. Just buy the tracks.

^ yes.

Just to add. Holy shit is Djay pro fun with a controller and spotify access.

You're technically not supposed to record mixes using Spotify. But, with that controller, one could, in theory, plug the booth output back into the iMac, and set recording input to the line/mic in on something like Audacity.
