LOL @ Jani...that is a trap for me as well...just stopped in to see what condition my condition was in and y said it right in your reply. IMO these are amazingly generous free offerings and as they are free the artist is allowed to establish usage terms and if they don't want folks selling them which is how models are used commercially, then it is

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
