Hi mimi456,
You can try to cater your Apple Music algorithm more to your tastes. The next time a Lo-Fi song comes on, dislike it. When a song comes on that you really like, love it. Eventually, Apple Music will learn your tastes and start to weed Lo-Fi out of your recommendations.
We learned this from the Apple Music User Guide that Apple published. You might consider bookmarking it for more great tips.
Love or dislike songs in Music on Mac - Apple Support
1. In the Music app
on your Mac, click an option (Albums or Songs, for example) below Library in the sidebar.
2. Do one of the following:
* Navigate to an item (such as a song or album), move the pointer over the item, click the More button
, then choose Love or Dislike.
* Click an item’s Disliked button
, Not Loved button
, or Loved button
to toggle between the options.
You might also double-check to make sure you've haven't accidentally marked Lo-Fi as a favorite artist.
Kindest Regards.
