::My understanding that the recordings are owned by DepEd and provided to the NHCP for distribution to the general public, and this is what "courtesy of DepEd" means, which are the words taken from the icon on the NHCP's home page.  The word "copyright" or "ownership" is not used nor is it said explicitly that it is "OK to copy."   "Courtesy of DepEd" means however "OK to copy", as I understand the words.  I am bolstered in my confidence of my understanding by the fact that it makes sense for DepEd to make recordings such as these for use by schools and others and that it makes sense of UST to offer its musicians for this public service.  I have further confidence that the NHCP would not provide copies so prominently on home page unless we are allowed to use the recordings as needed.
