Will I be absolved of responsibility if I say at the beginning of the clip, "Please turn off the sound if any music clip appears," so that I do not bear the sin of those who listen to advertisements containing music, and will my earnings from SoundCloud be lawful?

Earning income by listening to audio advertisements is not permissible if the profit is tied to listening to them. Similarly, earning income through this method is not permissible if the questioner cannot control the type of advertisements and knows beforehand that they will contain music. It has been previously warned that if one is unable to control and filter the advertisements and prevent the forbidden ones, while having a strong presumption of their presence, then earning profit from them is not permissible.
