If you want to use the music in commercial/monetized videos and remove the claim, you will have to buy a license. After buying a license, you will get an archive with high-quality .wav and .mp3 audio files.
Moreover, some licensed tracks have several versions of different lengths, which provides more flexibility for editing.
If you do not want to pay for the license, you can still use this music in your non-monetized videos.
