YouTube Music is going to be the next big thing from Google as far as music streaming services are concerned. Google is retiring the Google Play Music to some extent and allowing users to transfer the contents of their Play Music over to YouTube Music. Google even launched a handy transfer tool that will allow users to have a seamless experience. However, due to high demand, the transfer feature has been delayed.

If you head over to YouTube Music, you will see a warning that says that the transfers are momentarily delayed because of the high demand.
