Step by step guide on how to set up a music store

I feel like bashing my head against the wall.

All I'm trying to do is set up a free music store.

currently have mp3's (and yes we own the rights to the songs)

I don't understand what I'm supposed to do to set up the songs.

I'm going to reinstall zencart w/o any of the sample data because it's just confusing me.

Is there a tutorial out there that just walks us through adding a downloadable song?

Also, is it possible for the customer to select more than one song and the mp3's get bundled into a single zip file?

I've used search for about 2 hours, and all the information is confusing me

...I used to think I was pretty smart, until today :(

Here's a tutorial article on the topic: https://www.zen-cart.com/tutorials/index.php?article=119
It also contains links to related articles which you'll also need to read and follow.
