What does the 하지 after 노래 signify? Is it part of the negative conjugation?
Yes it's negative. 노래하다 = to sing, 노래하지 않다 = to not sing. ~지 않다 makes any verb negative.
How do you pronounce the "않다" part of the sentence? Is it "Anda" or "Ahda"?
It would sound like "Anda".
yooooo thank you . you just save my pc
