Unlock All Songs in the Jukebox
Japanese version: To get a Perfect on a song, you MUST wait until it has been chosen as a Perfect-eligible song which happens at random times (you'll know this when the frame for the stage changes and becomes wider and more colourful), otherwise your Perfect will not count. You have 3 attempts at getting a Perfect before its eligibility ceases, where it will either disappear for a while or change to a different stage. Note: You can attempt a Perfect on a stage even if you've failed the initial 3 attempts, but you must wait again until it is chosen as Perfect-eligible.
US version: Due to the numbers being changed around in the English version, I think it'd be appropriate to say the numbers. In the same order; Business Card toy 5553282338 - Tunnel Endless game 5557325937 - Samurai Slice Endless game 5557268724 - Battle of the Bands 5557625688.

Constant Perfect Challenges
Obtain a Medal on all 50 songs and there will no longer be any wait between Perfect challenges.
