i was wondering if i put some music frim this website in the backround of my youtube video.
is it ok if i make a profit from the video
I'm not sure. you better read the license
If you read the license agreement, as you should have, it is absolutely okay to profit using the soundfiles here. You must provide proper credit for each and every sound you use. Either in the video credits or in the description panel since you mention You Tube.
