In the Great Commission, we are told to go, but we are not told what medium to use in order to do that. It is specific in that we are to go, but it is general in the method. May we use a plane, a car, etc. to get where we are going? Sure, those are the methods to fulfill the command to go. The internet is used to help fulfill the part of the command that says to teach.
In Ephesians and Colossians, we are given a specific command. That command is to sing. There is only one medium that we can use to sing, and that is our voices. We are also told that it should come from our hearts. Mechanical instruments of music are not expedient to the command to sing. They are an additional form of praise that is not authorized in the New Testament.
I'm making no headway, and neither are you. Let's give this up.
