Does anyone know of a good VoIP client for doing karaoke? I've had a group of online friends that's been doing karaoke biweekly for a few years now. We've been using Raidcall, because it had perfect features including a queuing and a 'music mode' which allowed the speaker to play sound from their computer built in. Unfortunately, the Raidcall servers to be down for good now. Does anyone have any suggestions for alternative services? Free would be nice but not necessary.
