Hmm, personally I would exclude ZUN as an arranger, since he is essentially the progenitor of all the touhou music that gets arranged/remixed around.. (I haven't looked if he has re-arranged any of his own/old tracks though)
All are highly recommended !Here are my select dozen:
1.
REDALiCE from
ALiCE'S EMOTiON2.
MORRIGAN from
WAVE3.
Lix from
Levo Lution4.
nagi5.
JOYH-TV from
Team UD, SNB, etc6.
Kyuhouji &
Tokunan (who both form the famous unit
Demetori)
7.
Dobu Usagi from
dBu Music8.
Kurenainagi Tabibito 9.
Tsukasa Yatoki/
TSUKASA from
Arte Refact & Sound Online10.
