A SoundCloud link is great for both testing and just listening to it in the background.
You're right, it's probably not required for such few songs. I'm just used to it, is all.

Embedding soundcloud would be awesome to preview but you could also just link a youtube video. There’s also this tool which allows you to create a simple music player that will be launched on your page https://torcado.itch.io/scritch-editor
Also zipping your files would make it easier to download
