Variety:

Apple Music today launched the “Shazam Discovery Top 50,” a weekly, global ranking of 50 artists that it describes as “on the move and trending” — in other words, new and emerging artists.

While the company wouldn’t say much specifically about how the chart is tabulated, it uses “Shazam’s proprietary algorithms [to offer] a unique predictive view on rising artists and reacting tracks to Apple Music subscribers.” With 20 million Shazams each day and over 1 billion downloads of its app, that’s a fairly significant test audience.

It’s hard for the average person to “discover” new artists and music but this might help. The downside is it seems to be fairly limited, genre-wise.
