I don't know about the song previews, but the "Yes, get this offer" and "No, thanks" buttons on top of the page can be created using a popup builder.
It is actually called a floating bar popup, and you can use a tool like Popupsmart. It has a Shopify app, so you can easily find it on the Shopify Store and integrate it with your store. There is a forever-free plan and free templates so you can see if it works the way you want it to.
I'm adding an image of how it looks on my website. (I also added a countdown timer for max impact) Hope it helps!
