The Voice (8 p.m., NBC) — The Live Playoff Rounds start tonight with the Top 24 artists — including Sanford native Britton Buchanan and Chapel Hill native Rayshun LaMarr — performing. Things are a little different this year. Tonight, all artists will perform — six artists from each team — and four artists with the most votes from each team will advance to the Top 12 thanks to real-time voting on the mobile app and Twitter. So voting will have to happen fast — no overnight voting this time. Then tomorrow night and Wednesday night, the remaining 20 artists perform live. More real-time mobile app voting from you. Then on Wednesday night, four more artists with the top votes will advance and judges each get to pick one from their team to advance. That'll give us our Top 12. Here's our guide to all the ways to vote on "The Voice," including details on the special real-time voting this week.
