Apple Music: How to Purchase A Song After Streaming in Apple Music

Hi Mobile Blues! There is no "buy button" for an individual song in iTunes that I can find. I can only buy the entire Album. I've clicked "Go To"> clicked on "Show In iTunes Store" > My only choices are: "Play" "Gift This Song" "Add to Wish List" "Tell a Friend" "Share on Twitter" "Share on Facebook" "Copy Link"...

Okay, I figured it out. And this may be a useful tip for our community. Apparently, I had purchased the song from an album and also had an "Apple music" copy. Once I removed the "Apple music" copy from the playlist, I added the purchased version to the playlist and it worked. Apple could do a better job of making more clear what is "owned" and what is "streamed via Apple music" when looking at a song. Maybe an update for a future version of iTunes. I'd also like to see a way to instantly "one click" purchase a song from a playlist if I have it streamed as an Apple music song. I bet the artists would like that too.
