Is one who publishes Quranic clips on an application predominantly featuring music sinful, despite intending to gain reward and guide people, and fearing the mixing of the sound of the Quran with songs?

There is no harm in opening an account to publish the Noble Quran, for it might distract the user from unlawful songs. As for the concern about the sound of the Quran mixing with songs, it is not plausible, because the user chooses either this or that.
