I've been reading through a lot of copyright related posts, but have yet to see the exact answer I'm looking for:
I'm shooting and cutting an aerial videography reel for a local contracting company. It will be posted on their website as used to display what sorts of projects they've recently finished. I have done plenty of work for others but it's generally very platonic, and the media that I've done only really ends up on YouTube. This will be my first gig where I'm officially "employed" by a company, and I want to use music that won't get either of us sued.
As far as I can tell, Creative Commons allows commercial use as long as commercial use isn't explicitly prohibited. For example: I usually browse the CC tracks from smaller, upcoming artists on SoundCloud to find something that I can use without worry. Is my assumption correct? This sample reel won't be "sold" like a film or aired on television, etc. It will only remain on their site.
