Did you need a design of a music template or also the coding? Explain better your request..
The best way IMHO to approach this scenario is get a template that matches the design that you want, then look for a plugin/extension that does directory listing functions like the site you’ve referenced.
This way, you can always keep the functionality and change the site design in future, if you’d like to.
I have 5 music/band templates in my portfolio. Check it out. You might like one of them.
