Fantastic music for studying and writing. Definitely Peng.
If you like this, definitely check out the album Eternal Champ, by Sweet Valley. It's not an album based entirely on Zelda, but it's got samples from the game all over it.
I think I just enjoy the piano sample on taking off, I recognize it from Snake Oil by typical cats. The production is pretty damn good all over, some good rhymes and flows here and there, but some of the lyricism lacks substance, clarity. But it's still pleasant and compliments the production nicely.
