“The music industry is begging the US government to change its copyright laws” By Jamieson Cox on April 1, 2016
Christina Aguilera, Katy Perry, deadmau5, and dozens of other musicians are asking the US government to revamp the Digital Millennium Copyright act (DMCA), the piece of law that governs access to copyrighted work on the internet. Musicians, managers, and "creators" from across the industry co-signed petitions sent to the US Copyright Office arguing that tech companies — think YouTube and Tumblr, sites with vast reserves of content that infringes on some copyright — have "grown and generated huge profits" on the backs of material that's illegally hosted.

"The growth and support of technology companies should not be at the expense of artists and songwriters," reads the letter signed by Aguilera, Perry, and their peers. "The tech companies who benefit from the DMCA today were not the intended protectorate when it was signed into law two decades ago."

Whose job is it to police copyright infringement?
This is a complicated issue, but you can boil it down to one key question: whose job is it to police the appearance of copyrighted material where it doesn't belong? When the DMCA was created in 1998, it was much easier for artists and labels to handle isolated incidents of copyright infringement using the act's "notice-and-takedown" system. (It's self-explanatory: the copyright owner files a notice of infringement, it's processed, and the offending post is taken down.)
It's a lot harder to police the internet c. 2016. It's flooded with new, potentially infringing material every second, and the industry the notice-and-takedown system isn't responsive enough to help musicians' work retain its value. It's also noting that sites like YouTube have thrived on the "copyright black market," earning millions of clicks and views from content sitting in the grey area between posting and takedown. The sites counter by arguing they've given the labels the tools they need (like YouTube's Content ID system) to make DMCA takedowns faster and more effective.
It's unclear exactly what impact the industry's coordinated response will have on the status of the DMCA. Bloomberg notes that the US Copyright Office doesn't have the power to directly change the DMCA; it can recommend a set of changes to a subcommittee tasked with reviewing contemporary copyright law, but that's about it. If you take the industry's word for it, that change needs to happen fast, because the status quo is endangering the future of music. "The existing laws — and their interpretation by judges — threaten the continued viability of songwriters and recording artists to survive from the creation of music," reads the musicians' letter. "The next generation of creators may be silenced if the economics don't justify a career in the music industry."

Answer 1

Question 1: Christina Aguilera and The Other Musician Request to Government

They request or ask the US government to renovate(revamp) the DMCA act, that governs a copyrighted access to work on the Internet. The main reason behind their request or demand is to protect their work from infringement, which happen via online website like Youtube, Tumblr etc.. They made their request to protect their hardship, which is viable in the across the globe, where the infringment of their content (Music and Song), has been used by tech-companies in ease, to earn money.

Question 2: Opinion on the Issue

Analyzing the issue, in an un-biased way, will helps to put of a dilemma, about the issue. The Musicians and Song Writers tends to earn money & protect their content as well, in a legal way via DMCA (Digital Millenium Copyright Act). This DMCA was formed in 1998 to protect the creators content via copyright. This is in-turn helps to prevent the content from hackers and illegal usages. How ever the "Act" formed ealier, doesn't have a complete ability to protect the creators content on the whole, in this modern era. Site Like "YouTube, Vimeo & Tumblr " etc.. tends to follow the norms created by DMCA, but it still content creator experience the lack of their content security. United States DMCA, was much organized and stronger, when compared earlier, but the now Digital Era, makes every content, published with all the neccessary cities and legal requirement. But still the content faking, copying and lack of original author cites, is endaring the future of Music.

It would be better to bring on a strict DMCA enforcement to protect the creators content and industry.

Question 3: Self Opinion - " Job to police the Copyright"

Bloomberg clearly mentioned that US Copyright office doesn't have power to chage DMCA directly, however it has power to police the copyrights. United States government shall have powers to change DMCA, through US Copyrights Act, where the change tends to be implicated by the subcommitte, after review.

Inorder prevent the Quality content, song writers and musician, it's a duty of both U.S. government and U.S. Copyright office to police the Copyright.
