Google Music users have been complaining that the search giant's new scan-and-match service is mixing up different versions of songs, a recent report says.
Google recently launched a free music scan-and-match service. Like Apple's iTunes Match -- which costs $25 a year -- the service scans a user's computer and searches Google's servers for matching songs that can be streamed online without uploading music files.
According to The Verge, users are saying that explicit songs are being replaced with edited "clean" versions; the opposite scenario has been reported, as well. The Verge also points out that Apple's iTunes Match experienced similar issues following its launch.
Some users are expressing concern that Google is censoring their music, while others are worried that "clean" versions of songs are being swapped for the explicit versions. However, it appears that the issue may only affect songs that are scanned and matched, not songs that users upload to their personal libraries on Google Music.
