After speaking to the relevant teams we've decided to close this idea. Whilst it's not possible to remove an artist directly from your Home page, there are several ways to give feedback to the app that you don't like certain Songs or Artists.
- In your Discover Weekly, Release Radar and Daily Mix playlists you can click the 'Hide' button and select either 'Don't play this song' or 'Don't play this artist'.
- You can head direct to an Artist Page, click the three dots and select 'Don't Play This'.
We hope this clears things up and thanks for visiting the Ideas Exchange.
