Users of Google Music's cloud based storage system have criticized the service because it has been discovered that songs with explicit lyrics are replaced with more family friendly versions.

The service has a scan and match feature which is free to use and allows users can scan their music catalogue and then have online access to it, as long as Google can find a match on its servers.

The problem arose when users found that edited versions of songs such as Cee Lo Green's “F**k You” appeared on user's accounts rather than the explicit versions that were uploaded.

Google have claimed that the problem is not an act of censorship as the same problem has arose in reverse whereby users have uploaded the clean versions of songs and found that the explicit versions appear on their account.

The same problem has occurred with iTunes Match and Amazon's Cloud services.

As well as users having problems with Google Music, the service has also come under fire from the British Phonographic Industry (BPI) who claims that the service “doesn't make sense”.

The idea behind Google Music is to help combat the problem of illegal downloading but the BPI says that Google's failure to bury links to illegal downloads and torrents undermines artists.
