MaxKoMusic

Here you can find quality instrumental background music in different genres and moods. 
Free downloads, weekly updates.

Music is distributed under two "licence" types:

[Background music]
This music is free to download and you can use it in your non-monetized videos.
Perhaps your video will receive an automatic Youtube claim. This is OK, it only limits the ability to monetize a particular video, without other restrictions or sanctions: your video is safe.
If you want to use the music in commercial/monetized videos and remove the claim, you will have to buy a license. 

If you do not want to pay for the license, you can still use this music in your non-monetized videos.

[No-Copyright Music]
You can download this music for free and use it without any restriction in videos of all sorts, including monetized videos.
This music is absolutely free of charge, though I will appreciate it if you mention my name or share a link to this page in the video description.
