The artist profile may appear when you search for a certain name query. It is shown as a list item without a play icon. after tapping on it, you will appear on the songs list from the selected artist.
How to test:
- Open a story creation screen.
- Add a music sticker.
- Search for "cold".
- Check if you see an artist profile in the list.
This feature appears to be an A/B test and I have it only on my personal profile. Initially was spotted by @MattNavarra and @WFBrother.
