Whether you are selling or buying music on the Web, it is important to ensure that what you have is a copyrighted material. This is because while the Internet provides the easiest and the cheapest solution for the dissemination of creative works, it also facilitates easy infringement of rights.
On the part of those artists creating their original composition and posting them online, applying for a copyright is necessary to ensure that one will be recognised as the rightful owner of the work, as well as established one's right to claim revenue from its sale.
Music shoppers and users, on the other hand, are advised to shop for music only from online music shops that has been granted the right to distribute or sell the music on the Web. Doing so might be quite hard for online music hunters who are used to receiving free download. However, such move can prove to of advantage to users, especially if they are thinking of using music in creating videos or audio to be published online.
To get a good idea why it is important to shop only copyrighted music from licensed online music distributors, just take a look at YouTube's latest video posting policy. Just recently (or this must have probably been going for a while now), the video sharing site implemented a rule regarding the unauthorised use of copyrighted music in videos. The move means that original videos created by YouTube users using copyrighted popular songs as audio, which they were not authorised to use, will muted. So shop your music only from authorised music distributors.
