After hearing Evil Neuro's "Radio Voice", that got me thinking. Maybe not on Twitch but on a website or something the Neuro sisters can "livestream" the listener suggested songs for karaoke and their own covers. Like an internet radio sort of deal.
They can possibly do this unattended. Between songs they can rant as usual or react to the songs the way a radio host does (if the lyrics are fed to them via text or else via their speech-to-text).
Neuro (Samantha) and Evil (Eliv?/Henri?/Yui?) can both have themed radio shows where they feature the types of music they're interested in.
