I love it when people passionately argue for or against a song - it makes the game much more interesting, IMHO! As for voting against one song to save another - strategic votes and coalitions have been commonplace in Survivor games since we started doing them in 2007. It's just like the TV show in that regard. If you don't like coalitions, don't participate in them - but please don't complain when other players form them. They're a legitimate part of the game and always have been.
This game is not for everyone. If you can't handle people voting in ways you don't like and you get highly agitated if your favorite songs are voted off, it's best for your blood pressure if you refrain from playing.
As you can see, Windeagle, this game has provoked some controversy in the past. People can be very protective of their favorite songs! Still, in the end, most folks have a good time with it.
