[linux-audio-dev] License for sounds

I'm trying to figure out what license to use for the demo sounds and songs that come with Audiality. I don't think the songs are of much interest beyond demonstrating the engine, so I'll probably just ask that people don't use them in their projects without permission. However, the sounds (or rather, the scripts that render them) are intended to be usable in about the same way as the rest of Audiality. That is, as is or modified, in Free/Open Source, freeware and commercial projects. No royalties, no advertising clause or anything. Here's the problem: I'd like derived sounds to remain open source, but I'm not sure it makes sense to require it, like the LGPL does. The X11 license might be more sensible.
