Blew My Mind is the default encore song. After every five songs played, a song will randomly be unlocked out of a set of four (marked as SEC1, SEC2, etc.), and on the 25th song, a new encore stage will be unlocked. Thus, the order of songs below should not be used as a guideline of when songs are unlocked, because they may not be in order.

ASTRO JOURNEY
Go around to four cities and dance your heart out at each of the seven clubs in each city. You can start at any one of the four cities, but the songs in each city are unlocked in the displayed order. When you enter a club, you play three rounds of songs, and then an EXTRA STAGE which is the displayed song.

After clearing Sakura Tempest, Dichotomy, TRIPLE TROUBLE, and SAHASRARA, Heavendor and Superbia are unlocked. After clearing Rome EVOLVED and Imperator Gloriosus, the Forbidden Tower is unlocked.

Alternately...

BONUS STAGE and ENCORE STAGE
In a normal round of play, you will receive stars based on the grade you receive. A AAA gives you 4 stars, a AA gives you 3 stars, an A gives 2 stars, and a B gives 1 star. If you have at least 3 stars at the end of your second song, you will unlock the BONUS STAGE. This plays like a traditional extra stage, but you will be forced to pick one of three secret songs. Any song has an equal chance of being selected for a BONUS STAGE, with the exceptions of: Sakura Tempest, Dichotomy, TRIPLE TROUBLE, SAHASRARA, and any songs found in Heavendor, Superbia, and the Forbidden Tower. When you clear a BONUS STAGE, you will unlock that song if it was not already unlocked and receive the usual amount of stars plus one. If you have at least 9 stars after your final song, you will access the ENCORE STAGE. The ENCORE STAGE follows the same rules as the BONUS STAGE, but there is a greater chance of being able to play songs that are not accessible during the BONUS STAGE.

BEMANI crossovers
BEMANI crossovers are unlocked in a different manner. After clearing two clubs in ASTRO JOURNEY or unlocking two songs through BONUS/EXTRA STAGE, you will receive a gift from one of the seven other "main" BEMANI series; you can choose which one. This gift is a crossover song, and they will always be unlocked in the order shown (you can't get Cosmic Cat from your second IIDX gift, etc.).
