Caching MP3 files on CDN

Does Cloudflare have support for MP3 files caching on any of its plan pro, business or enterprise?

Use a Page Rule with “Cache Everything” like
https://domain.com/music/*.mp3

Don’t misuse it, as it is not intended to cache and serve tons of Gigabytes of media files.

This phrase is very suspicious to me:

Don’t misuse it, as it is not intended to cache and serve tons of Gigabytes of media files

because I have to use it for my media content where my users are listening to mp3 course lectures from mobile apps. So I need to assure that there will be no disruption in service. My mp3 data is about 500GB.

You need to clarify your use case with sales/support. If not you run the risk of getting your account eventually suspended.
