ANSWER:

This is not permissible as it would ultimately make you want to listen to the original one with music or relate what you are listening to to the real thing which is reminding you of it.

QUESTION: Is listening to a song permissible if people have taken this song (with instruments) and removed them digitally? There is no background vocals IMITATING instruments like u see sometimes, its just the voice that is singing in a melodious way and in the rhythm (with some autotune to make it sound better).
