I've used Soundstripe for years now.
I've used Soundstripe for years at this point and I have zero complaints. I use their site for my own content creation, as well as for my professional video production company. It's an easy site to use; most of the time, I can find a song or sound effect quickly. Unless I get stuck in the rabbit hole every editor knows about, but that's not Soundstripe's fault lol! I like the stock video options to use with some of my video production work.
