With the Internet now being a viable source for music, net labels emerge. Depending on the ideals of the net label, music files from the artists may be downloaded free of charge or for a fee that is paid via PayPal or an online payment system. Some of these labels also offer hard copy CDs in addition to direct download (for example, Baltimore's Schismatik record label ships CDs for a nominal charge). Most net labels acknowledge the Creative Commons licensing system thus reserving certain rights for the artist.
