Does the use of educational video clips containing music affect the ruling on their use if the student is in urgent need of an explanation of the lesson?

Listening to music is forbidden, and sin is incurred by intentionally listening, not merely hearing it unintentionally. If the aforementioned lesson contains music, you are not sinful for hearing it unintentionally, because the sin falls upon the one who directly uploaded the music. And whoever disseminates something forbidden and then repents from it, his repentance is accepted, and he will not be held accountable for what he disseminated.
