Remixes from Dance show time at HOTEL Love songs?

[Tom Punks]

this may have been asked before but the search function never works for me so idk

anyway, I was wondering if the remixes from the Dance show time megamix at HOTEL Love songs are real, released remixes? and if so, does anyone know which? the only one I semi-recognized might have been SEASONS from ayu-mi-x 7... are the rest from that series as well? thanks for any help!
