Your music shouldn’t just sound good, it should look good, too. Upload artwork for your tracks and albums - the higher resolution the better. You can zoom and reposition your artwork or images during the upload process to get the perfect fit.
The descriptions of your tracks and albums are the perfect place to share extra information: think about including a track’s backstory, add credits, lyrics, gear lists, or guest lists. Give a shout out to collaborators and feature artists, by linking to their SoundCloud profiles.
Whatever way you choose to present your tracks - be consistent with your information and in your style. It will look more professional and be more.
