I guess there is no way to listen to a preview of a song before you buy it on iTunes, right?

I saw an article in apple support that said all I have to do is hover over the song and "preview" will appear.

Nothing appears. There is no menu item for preview.

I have now spent one hour trying to buy a song. I finally found the "search" button (in the upper left corner) but now I can't preview the song.

Does anyone know where else I can buy music? Somewhere where they actually want to sell music and not subscriptions?
