How do I find an artist or specific song using Apple Music?

For the life of me I can't figure out why Apple screwed up iTunes the way they did on a Mac. I usually do most of my reviewing and purchasing on my windows based PC but in this case I have to use Apple Music. I love my MacBook Pro - works well for all my VSTs etc but ***** as a music player - especially when I want to find an artist or a song. It's just impossible.

I have the iTunes "shortcut" or what ever you call it in "appleasse" on the left hand side. When I go up to the top left and type in the band I want to see (who might have the latest material) it defaults to my collection.

Like so many other people... how to I find an artist or specific song using Apple Music

Thank you.

I'm about ready to switch over to Amazon Music. I have purchased 52,538 songs on iTunes. Do the math. You would think you'd want to keep a customer like me.

Thank you,
