10 second loop sound source

Can anyone recommend a source for 10 second sound loops. I'm after gentle background melodies. Thanks.

For what? If its for land that you have control over, consider streaming audio instead, since you won't be faced with the 10 second limitation, and to be honest, if your land had (even the most pleasant) a 10 second music loop, I'd make sure and avoid it. I believe that Robin Sojourner came out with a windchime that might be close to what your after, which mixes samples of various windchime elements played randomly, so the effect is more like real windchimes, rather than being annoying.
