Today is one of those nice days where Amazon's Free App of the Day is far more than just a single app. Of course, just one of them may make it all worth it. Five Nights at Freddy's 2, the popular survival horror game, is among the free choices and you even get a $1 MP3 credit just for downloading. Yep, even if you don't have the slightest interest in it, you should probably download it and buy yourself a song.

The occasion is the Appstore's fourth birthday, so another side benefit is that a single download enters you into a drawing for a $25,000 reward. Further, this is more than free apps of the day - this one will last until March 21st. Amazon values these free apps at $105, so they aren't messing around.

In total, there are 34 free apps and games. Some other highlights include EasyTether, a blast from the past that usually goes for $9.99 which allows root-free Internet sharing to desktop computers. NeoCal, another app that is typically priced at $9.99, is an advanced calculator app that may make up for its aging interface with its various capabilities.

Here's the full list of included free apps and games, with their full prices (that is, not the price you'll pay today).
