For many in the music business, the repercussions of Google being allowed to get near a 50% stake Sony/ATV would be deeply worrying. Sony/ATV manages 4m music copyrights written by the likes of The Beatles, Taylor Swift, Michael Jackson, Ed Sheeran, James Brown, Elvis Presley, Lauryn Hill, Oasis and Eminem.
Remember that those 4m copyrights are spread through countless recordings and, therefore, master rights deals with labels. That would have been the first headache for the likes of Universal Music Group.
