I think mp3s are a better choice.
The file size is much smaller and you can host them cheaply.
Unless you absolutely need video, mp3 is the way to go.
You can host a lot of your mp3s on centralized services like google drive and link them here. You get the benefit of using their bandwidth for free, without them getting any ad revenue.
