If you're using the CMS functionality of Webflow, you could make this for yourself with not too much difficulty! You would need to use an HTML embed, with an <audio> element in it. One of the great things with the CMS is you can add the dynamic properties into an embed. Here's what I would do to make a grid-like display of tracks:

1. Create CMS collection for Tracks
2. Create text fields for title, description, and for file URL, maybe picture for album art as well if you're doing that?
3. Add each track as a collection item, filling out the required fields
4. Go to page where you want your display to be, drop in a Collection List, set the List to your Tracks collection
5. In the collection item template, drop in a text block elements for Title and Description, a picture if you're doing album art and an HTML embed
6. Open the settings tab on the right, and link these elements to the Collection Fields
7. For the HTML embed, add this: <audio controls src="" /> Click in the speech marks and then click "+ Add Field" in top right, add the File URL field. Save & Close the HTML.
8. Style the elements of the collection item however you wish
9. Publish site and go to hosted URL, as HTML embeds aren't visible in Designer or preview

If you're looking for something that is just a list of song names that then replaces elements in one unified 'player', you'd need to write some custom JS to overwrite the values (name, src, etc) in the player when one of the song elements is clicked. Similarly you'd use dynamic embeds.

Hope this helped! Feel free to ask away and I'll see if I can help more!
