Free-stock-music.com offers royality-free music for your videos or multimedia projects (blog, vlog, podcast, social network, etc.). All you have to do is to put the attribution in the credits.
“All you have to do is to put the attribution in the credits.” – this is not trade-free.
They have some trackers or even ads on their website. Plus, when you download you are faced with a popupu asking you to follow them on social networks (that are trade-based) and/or donate to them. it is a bit pushy and they want your attention a bit. They also offer some music for a price. So they are barely trade-free if at all. They also sell some subscriptions.
