You might have a good solution for your needs with Reelcrafter.
For balance, in case others read this and are looking for different options ...
I think there are services that let you manage and track links for audio to clients and prospects that can be separate from a website (or together).
Personally, I didn't love Reelcrafter's limitations. So I never got on board with their deal. Maybe it's better today? It was a couple years ago that I explored them.

There's tons of features under the hood.
Here's an example using your background and a VSL logo that I whipped up:

As for a website, I already pay for web hosting for my LLC and manage several sites including my and my business partners' dance music record labels (digital and vinyl).
