Freeware music website I am considering using for lessons. I am still vetting the content on there but it contains remix samples and the inevitable remixes created from them all under the Creative Commons licence. Provided the licence says BY-NC you can use it for home use (Podcast background music, video track, etc) but can anyone clarify if schools are covered under commercial use for creative commons in lessons? I think LGfL have a Creative Commons library on their site.
