Thanks for the heads up. I don't remember which keywords I used when I found that sound clip, but it did say that the use was alright for commercial projects too. But it does sound VERY close to zelda jingle and I actually ironically enough named the sound clip 'Zelda jingle'
I've previous found some clips from freesound that seem to be ripped from other games or movies too, without the author saying a thing about it, so it's certainly not impossible that's it's from Zelda. I'll switch it into something else just to make sure.
