Amir bin Saad bin Abu Waqqas reported,

I witnessed Thabit bin Wadia and Qarada bin Kaab al-Ansari at a wedding, and there was singing taking place. I questioned them about it, and they replied, "Singing at weddings has been permitted, as has weeping over the deceased so long as it does not amount to wailing."

Sahih

عن عامر بن سعد البجلي يقول

شهدت ثابت بن وديعة وقرظة بن كعب الأنصاري في عرس، وإذا غناء، فقلت لهما في ذلك فقالا: إنه رخص في الغناء في العرس، والبكاء على الميت في غير نياحة.
