Grooveshark has received favorable reviews from PCMag, with 3.5 out of 5 stars, and SiteJabber, with 91 percent positive reviews. The few user complaints listed on SiteJabber relate to advertisements and delayed loading times. DigitalTrend's Grooveshark review noted the lack of free mobile applications and variable song quality.
Regarding the overall function of the Grooveshark website, DigitalTrends reports that it holds up well against other free music streaming sites, such as Spotify and Pandora. Grooveshark's collection of songs is extremely comprehensive because it is uploaded by the many users of the site; this is also responsible for the potential lack of quality, inconsistent song naming and the lack of free mobile apps for users. Grooveshark launched its own mobile application, which is not free. Unlike Spotify and Pandora, the profits of this app do not always go to the artist, which is the reason Android and Apple do not offer Grooveshark in their app stores.
Non-user complaints about Grooveshark typically involve its copyright status and come from representatives of various record labels. Because Grooveshark's content is user-uploaded, it is possible for users to stream unlicensed music for free. However, Grooveshark CEO Sam Tarantino has stated that the company fully complies with the Digital Millennium Copyright Act, meaning that songs reported for copyright infringement are removed from the site.
