question on remix cd's..

[jerms]

1. the "M" A&B on ayutrance 1 & 2 are the same versions right? why the heck would they put the song on both.. *confused*

2. on ayumix III i think it was..it has like 5 surreals. just wondering if tehy sounded the same or what? thats so weird to have it like that..tahts like..a "nonstop surreal single"..ahha makes more sense then the surreal single she has out witha buncha duty mixes instead of surreal ones

3. who mixes teh AO versions? are they all done by the same person on the albums? ayu-mi-x 4 AO+selection didnt give many credits.. =\
