Google pulled the Grooveshark Music app from the Android Market yesterday, citing a violation of terms of service. As to what specifically Grooveshark was doing that got them removed is unclear. While neither Google nor Grooveshark are saying very much on the matter, speculation is that it could be pressure from the music industry. Perhaps coincidentally, Google’s general counsel, Kent Walker, is slated to testify before the House Judiciary committee today on a case about sites which purportedly traffic pirated and/or counterfeited goods. For the uninitiated, Grooveshark offers free music streaming by letting its users post their own files. The music service has seen its fair share of lawsuits, most recently with EMI and Universal Music Group.
