That’s really good; and corny too. One suggestion is an on/off switch for the music
Cross talk is a magnetic field, generated by one wire impacting the data integrity of a second wire in near proximity. As you pass current through a conductor, a magnetic field is formed, when this field get near another conductor, it induces an electric current in this second conductor, changing the signal in the wire. So if you get to wires to close together and not properly shielded, the signal on one will impact and change the other, and vise versa.
