NieR was a mixed bag on release. It featured amazing storytelling, endearing characters, and a unique story and world, but this was all muddied with some average gameplay and an incredibly slow first half. However, the music of Keiichi Okabe and Emi Evans was good enough to outweigh almost any flaw. Amazing vocals and instrumentals were omnipresent throughout the entire experience, making for a real standout soundtrack. It's not surprise, knowing this, that not only is the soundtrack available on iTunes, but a remix soundtrack titled NieR Nightmare Tracks is available as well. The music of NieR is getting another addition as soon as next month with a tribute album titled '-echo-'.
