Keep your receipt of purchase and license handy so that you can show YouTube you do have the right to use the track. I've had to do this with a lot of my music and they'll lift the flag and you'll be set to use go!
Click the ‘Pricing’ next the beats and select the license you are looking to purchase. Repeat this step for the desired number of beats to put them all in the shopping cart. Once ready, click the cart icon in the top right corner and click ‘ checkout’. You will be redirected to a page where all your selected beats/licenses are listed. Please review, if everything is ok, you can select below if you want to pay with either your PayPal account, Cryptocurrency or any major credit card. After payment, you will be given a download link where you can download the files from.
