This is a cool song, but the picture is very much misguiding; this is in fact the version of "Great Sea" from Phantom Hourglass, not Wind Waker. Just letting you know, because it's a good song but it is labeled wrong. If that can be changed, that'd be great, thanks!
Actually, there are to versions of "The Great Sea" by Shadow in the library. The other one is under the name of "Sailing Theme" and is admittedly lower quality than this one, though they are both definitely PH, not WW :P
For some people, it's real easy to have gotten them confused, but since PH was my first Zelda game, I just kinda know the songs apart practically instinctively.
I know them apart too; I was just saying that this is definitely PH, while the tag and the picture say WW. :P
