Sharing your music with the world is critical. While standard services such as Tunecore, Distrokid, and CD Baby exist, a few free distribution services are available for those on a budget.
The beauty of these platforms is that none of them charge a fee until the artists begin earning money. These services are excellent for indie artists, especially when growing a fanbase.
These can benefit a rising artist greatly because most artists likely won't make a lot of money in the early stages of their music career. The beauty of Level and RouteNote is that musicians keep 100% of their royalties. Stem only takes 5% of earnings, which is still a relatively low percentage to payout.
Each service will place musicians' tunes on the major streaming platforms and offer artists different features to help them reach the masses with their music.
Give either of them a chance, and let us know which one worked for you.
