Webhooks for voice channels

Please allow us to create and use webhooks for voice channels.

Ideally through both, user and bot accounts.
These webhooks would be able to play audio on behalf of a website or an application.

Usage scenario:

A good example would be bigger guilds. Most have to employ multiple music bots, because two or more voice channels want to listen to music at the same time. Creating a webhook for a voice channel would allow a bot to easily create users to play music through.
