Sorry for the delay in getting back to you, I've been waiting on responses from a few folks because I didn't want to misinform you. I'm still awaiting confirmation for Renegade Stage but wanted to pass this part along.
For the talent show, you have two options :
1. You can bring a USB with the music file on it and hand it to the team running the talent show. They will run the audio from their computer.
2. If you want to use an unlisted YouTube video, you can email the URL to the team running the talent show and they will cue things up for you.
3. You can also email the MP3 file directly.
The email address will be provided at last call auditions taking place on Friday at 7pm at the Con. Anything submitted prior to the last call audition will be rejected - so don't send anything prior to the Con!
Will get back to you when I hear more about how Renegade Stage works - though I imagine it will be fairly similar (i.e. bringing the music with you).
