Can't purchase a song or album or sample it

I understand it's confusing, but Apple has not changed the ability to sample or purchase music the same way you always have.

Please read Add and download music from Apple Music or buy music from the iTunes Store. It illustrates exactly what to do.

Can you post a screen shot of what you see.

I remember when Music was announced, there was a button that seemed to indicate you could only subscribe to Apple Music, but it was just a button to continue using the Music App. Somewhat confusing.
