Taylor Swift and other artists now targeting YouTube

Taylor Swift has faced down Apple and Spotify. Now, she's got bad blood with YouTube.

Swift joined more than 180 artists and bands — among them Christina Aguilera, The Band Perry, Jennifer Hudson, Elton John, Yoko Ono Lennon, Paul McCartney and U2 — in lobbying lawmakers to update the Digital Millennium Copyright Act (DMCA) to address the issue of unlicensed copies of music on YouTube.

The DMCA, passed in 1998 to protect digital works from infringement, has a "safe harbor" provision that protects Internet service providers and Web sites from copyright violations if they take down content when notified of the existence of pirated works. However, as YouTube has grown into a go-to source for legal and unofficial music, the take-down concept has become unworkable, artists say.
