Person1: I read it myself on the financial page.They ' re really going to join together . U-Tunes was bought out by Murphy's , they will take over the company as of next month .
Person2:The competition must have been too stiff for U-Tunes.Otherwise why would they allow themselves to be taken over by their sworn enemy ?
