FYI, there's only one night per season where "The Voice" only sends home a single singer. For a show with spinning chairs, boxing rings, duets, playoffs and steals, that's just way too stale.
Instead, the NBC singing show opts for double eliminations, which are determined each Tuesday night by announcing the three finalists with the lowest votes, then triggering viewers -- whether watching live on the East Coast or otherwise -- to tweet their pick to save a singer. After the fragile five-minute window, the performer with the most tweets stays in the competition, while the other two are sent home. (It's one vote per artist per Twitter ID, by the way, but have fun filling your profile with countless RTs that don't count.)
