To my understanding Nico☆Sound (にこ☆さうんど, the old one) was kind of illegal, and NicoSound (the new one) Them similar names （ಠ_ಠ） is Nico Nico Douga's official one.

Also on the official one not every video has a download provided. orz

And yea ACC seems to be more HQ But I don't think my mp3 player can handle ACC orz

RIP Nico☆Sound I'll miss you TAT
