There's this user called Jackie1188 on Newgrounds who submitted wonderful piano songs... 5 years ago. The user seems to have a personal blog, too, but it wasn't updated since 2008... I tried to send an email, but I guess I won't ever get an answer for it.
And that brought up a question for me. Why don't we consider songs on Newgrounds available if the user doesn't mention we can't use it? The copyright text doesn't specify:
"Attribution: You must give credit to the artist.
Noncommercial: You may not use this work for commercial purposes unless you make specific arrangements with the artist under another license.
Share Alike: If you alter, transform, or build upon this music, you may distribute the resulting creation only under a license identical to this one."
What am I missing?
