What most people don't realize is that most Zelda games borrow music from older ones Link's Awakening has music that was featured later on in Ocarina of Time (Malon's Theme, due to the obvious reference of Marin), Wind Waker (this game borrows music from all Zelda games), and Majora's Mask (Wind Song).
I could be wrong about Malon's Theme but I know for sure about the rest. Hell, Wind Waker has the Link to the Past Opening theme and Ocarina of Time has the Kakariko Town music.
This mix is great. Link's Awakening needs more remixes. My favorite remixes are ones that have the most improvement. I doubt many people like the metalic sounding music of the GB game itself.
