Downloading music from apple music

I am not computer literate at 92 years old... I have found a song on Apple Music that I want to add to my library, however things have changed since I last downloaded a song and I can't figure out how to do it. I thought there used to be a place with the magnifying glass where I could put in the name and when I clicked in the mag... glass a list came up with a download button next to the list of songs and I could click on the button, agree to the price and get the song. I'm not finding that now. What has changed and can someone help me? I hope I have made myself clear. Have a peaceful Labor Day.
