Downloaing an mp3 file ionic and android

Hey Guys, I have an mp3 file on a remote server and im trying to download it in ionic.
I’ve tried the following so far:

<a href="myurl" download="foo.mp3" target="_self" /> </a>
<a href="myurl" download="foo.mp3" target="_blank" /> </a>
window.location.assign(url);
window.open(url);

None of these get the file to download. i think i have to use the codova FileTransfer plugin but i have no idea how to use it with ionic.

Could anyone help with integrating the FileTransfer plugin or offer an easier solution for this?
