Firstly I would suggest that you read about Wix Corvid if you are all completely new to this.

As for the code itself, how are you looking at having the song on the page to redirect the user to the external song page?
Shown in previous reply, if you simply have a choice of songs on your page and you have a basic button underneath, then simply have the button setup to have the user directed to that page.
export function song_onclick(event) {
wixLocation.to("http://wix.com");
}
// With the properties panel onClick event handler.
See here for more info about working with event handlers etc.

If you are wanting a to go to a certain page like Fastest Web Hosting Services | Buy High Quality Hosting automatically open a external page URL then do the other option in your page code.
Simply have a blank page so that there is nothing on it and then delete everything already in that page code panel and add this into it.
import wixLocation from 'wix-location';
$w.onReady( () => {
wixLocation.to("http://wix.com");
}
As there is nothing actually on that page, it should load very quick and go straight to that external URL link almost immediately.
Finally, if you have a lot of external links for a particular piece of music, then I would suggest you do similar to what they have done on your link page of https://www.shapeofthesun.com and have labelled buttons for each option which will direct them to the appropriate external URL when they are clicked on.
