To be able to play songs on your webpages, you'd have to upload them on a cloud hosting platform like Dropbox or Google Drive, and then link it to your webpage. Here's a guide for uploading content using Dropbox:

For Drive, it's similar, except if the sharing link looks likes this:
https://drive.google.com/file/d/XXXXXXXXXXXXXXXXXX/view?usp=drivesdk

or this:
https://drive.google.com/open?id=XXXXXXXXXXXXXXXXXX

we'd need to change it to:
http://drive.google.com/uc?id=XXXXXXXXXXXXXXXXXX

where XXXXXXXXXXXXXXXXXX is the id of our file.
