You can buy a track here by choosing one of the different license options.
In most cases a “Music Standard License” will cover you for use in youtube videos.
It’s best if you read about it here on the official page:
With your purchase, you get a license sheet that allows you to clear a claim when the music is registered with content id, so you won’t have any issues. And as CWMusic mentioned, the Music Standard License is the right one for youtube.
This is not possible. A license will cover one end product, in most cases that’s one video. There is a series policy that allows you to get one license for up to 52 episodes of a same series within a year.
The only way to get something approaching “permanently” would be to create an intro that’s always the same with no modifications whatsoever, no different text overlays or voice-overs. The rendered intro could then be considered as the end-product and then slapped in as is at the beginning of any number of videos.
I buy a track off AudioJungle (Music Standard Licence)
**I put it as the backing to my original video on Youtube that has ad revenue ** I can then use that track only on that 1 video? I have to use a separate track for each video (1 licence for each separate video?) My video gets 6 trillion views (I wish) - I’m still covered by the licence? I put a link or copy of the music licence in the Youtube description (stops having to clear any claims?)
Sorry for the lengthy text, but would this be correct?
