I feel you. I think I experience the same.

I’d say it’s almost summer now, go out and visit some music festivals. That’s a place where I found some inspiration and new (to me) artists.

Also having friends with a similar taste in music helps.

I have a Spotify subscription and that helps me listen to a broad range of music on a whim. But I think the Spotify algorithm isn’t helping me in discovering new artists. I rarely find anything interesting and new that way.
