There is a lot of confusion with what type of Music one can listen and what Instruments are allowed. These days even on Islamic channels we have music in backgrounds being played even if a Ziarat Documentary is being shown. Qawali in old days had very simple instruments and now days a huge variety is used within in. I want to have clarity please.

If you find no clarity then abstain from it all as a precaution. Sayed Sistani’s ruling states that if the music is like the music played in places of entertainment and amusement, then it’s forbidden.
If you can’t determine, then practice precaution.
Just because it is on an Islamic channel or in an Islamic state doesn’t make it permissible. We should practice precaution where we are unsure.
