Proton offers DJ mix uploads to its labels and artists. Anyone who meets the below criteria though are able to start uploading mixes:
Label Managers - If you run a music label at Proton, then you can start uploading mixes during the beta. Label managers who work at other distributors can contact us about switching to Proton: launch@protonradio.com
Artists on Proton Labels: If you're an artist signed to any of Proton's nearly 4K music labels, then you're invited to the beta and can start uploading mixes now. Artists signed to music labels not distributed by Proton, can invite their label managers to contact us about joining us: launch@protonradio.com
Promo Pool DJs: If you receive promos from music labels distributed by Proton, then you also can start uploading DJ Mixes during the beta. If you're receiving promos from music labels NOT powered by Proton distribution, you can encourage the label owner to contact us & join Proton: launch@protonradio.com
If the above 3 categories don't apply to you, then you'll need to wait until a future phase of our product.
