Christmas Rhapsody is the 7th purchasable stage in Piano Tiles 2. It is a remix adapted by Pi, consisting of We Wish You a Merry Christmas, and Hungarian Rhapsody No.6. The song starts at 6 tiles per second (360 tiles per minute) for a little bit and the player plays the "Merry Christmas" part. Afterwards, the song speeds up to 6.67 tiles per second (400 tiles per minute) after getting the first star. Then, after passing through a bit of normal gameplay, the song streams the player in a waterfall of double tiles, with one part having only one note instead of a double to trick the player into tapping two, and losing. It's considered as the hardest song in Piano Tiles, due the speed was increasing when you get 2 stars.
If the player survives, the song speeds up exponentially (more than any other song in the game in fact) to 8.67 tiles per second (520 tiles per minute. The player plays a very fast Hungarian Rhapsody No.6, then a modified Merry Christmas, and then back to the modified Hungarian Rhapsody No.6.
Because of the demented acceleration rate of the song, Christmas Rhapsody is often considered to be one of the hardest songs in Piano Tiles 2. According to some conversations, Christmas Rhapsody not only has the craziest gameplay, but also gives the hardest gameplay to get the third crown. Very little players can get 3 crowns in this song.
Getting the third crown of Christmas Rhapsody requires the player to be persistent, and probably a total lunatic at this game. At three stars, the player encounters 9 tiles per second, and the speed picks up slightly to 9.33 tiles per second. After getting crown number two, the player has to deal with 10 tiles per second. After finally obtaining the third crown, the player goes with a speed of an unimaginable 11 tiles per second. Along with Star Clock, Christmas Rhapsody is one of the songs that have the speed over 11 TPS when you get 3 crowns.
Beyond that, the speed of the song will pick up more and more. After two laps, the song becomes so fast that the TPS may go beyond the human threshold for most players. In other words only hackers or bots can do six or more laps.
Very few people have beaten Christmas Rhapsody, with a very small pecentage of those few people actually obtaining the third crown.

This song even challenges the best players in the game like EK. The player will really have to practice for weeks to beat this song. At this point, it is nearly impossible to most if not all players to get the third crown. The only way for players to master Christmas Rhapsody is to encounter the ludicrous speeds that are found in Christmas Rhapsody. The best solution would be to do the Master Challenge.
