Research on sound

I was browsing the internet and i came across sounds which were copyright free i was interested due to i could use some elements from these sound tracks or even use them within my thriller opening. I have a screen shot above showing the website i visited and the soundtracks which i listened to.
this is a link to a soundtrack i had in mind to use for my thriller opening.
