hi, welcome 2 ahs
personally, id recommend u get [ayu-mi-x II version JPN]
it has some really great remixes of [monochrome] [And Then] [P.S II] [appears] etc...
US+EU version is a bit crap imo, the versions on that disc are like radio edits or something, u should check out [the past & other side of ayu] its a bootleg compilation of [the other side] series, (o.o.p now, which is y i recommend da bootleg...) which featured some previously unreleased extended remixes from [ayu-mi-x II version US+EU] (which r by far superior 2 the crappish radio edits...)
