How to buy iTunes songs with no Apple Music Subscription

I refused to subscribe to Apple Music, I refuse to rent music, I want to purchase my music for good.

I just got a brand new MacBook computer, I open Apple Music, I can play all my previously purchased music, I see the link to iTunes Store on the left panel, but when I click on the iTunes Store link, it doesn't allow me to search. I have to use the Apple Music search to find the song that I want, and it will find it, but doesn't give me the option to purchase it, it just wants me to get a subscription so that I can listen to the song which I refuse to do.

I know this is an effort to make it difficult on the user, but there must be a way to buy a song from iTunes on a Mac, I just can't believe that they are refusing to sell you music ?

So what is the truck to get into iTunes, search for a song and buy it on a MacBook ?
