In general, music is protected by copyright law, which gives the creators of the music exclusive rights over its use and distribution. This means that any unauthorized use of a musical work, such as uploading it to YouTube, would be considered copyright infringement.
However, the issue of copyright in music is complex and can be difficult to determine in specific cases. The specific rights that a copyright owner has over a musical work can vary based on a number of factors, such as the jurisdiction in which the work is protected, the type of use being made of the work, and the specifics of the licensing agreement under which the work was created.
In the case of Lofi hiphop music on YouTube, it is likely that a significant portion of the music that is uploaded to the platform is infringing on the copyrights of the creators of the music. This is because much of the music that is featured in the Lofi hiphop genre is created and distributed without proper licensing or permission from the copyright owners.
In order to avoid infringing on the copyrights of others, it is important to carefully research the rights that are associated with any particular piece of music before uploading it to YouTube or using it in any other way. This may involve consulting with legal experts, searching for licensing information, or seeking permission from the copyright owner directly.
In conclusion, it is not accurate to say that all Lofi hiphop music on YouTube is copyrighted. However, it is likely that a significant portion of this music is infringing on the copyrights of others, and those who wish to use this music in any way should be cautious and do their due diligence to ensure that they are not infringing on anyone's rights.
