OurSong is a music co-creation platform that uses the blockchain technology, hence, any creation uploaded on OurSong will be permanently recorded on a public blockchain. You cannot modify or delete any of your creation records on the blockchain.
Thus, regardless of whether you intentionally or unintentionally use someone else's copyrighted content, you will have a permanent record of infringement.
The original creator can use this record as an evidence if they decide to take legal action against you. Therefore, we suggest you only upload contents you own or have the right to use.
