Is it permissible to sing or listen to songs in weddings?
In the name of Allah, the Most Beneficent and the Most Merciful
Happiness is a Ni’math (Blessing) from Allah the Almighty and it is necessary to be thankful to Allah for the Blessing and not to indulge in prohibited Haram activities and be ungrateful to His Blessing and invite His wrath. As for singing (musical) songs or listening to them, both of them are Haram and impermissible in Shari’a hence it is obligatory to refrain from them.
Allah knows best.
