Where can I listen to iTunes song previews without having to sign up for the 'Try it Free' subscription?

Something has changed with iTunes recently. I'm not able to listen to song previews without being prompted to sign up for the 'Try it Free' Apple Music subscription. I can't even find the iTunes Store listed on the left sidebar anymore, or on top, underneath the play bar like before.

Where can I preview the songs without having to eventually pay for a subscription? Is this the way it's going to be from now onward?
