The character 樂 has multiple meanings depending on the context. Commonly it means "happy/joy". When combined with other characters, it would then mean "music".

I don't know this young man's original intention when he picked what appears to be 喪 (sad/mourning) and 樂.
I could only assume he wanted "sad & happy", however this appears to be "dirge", or "funeral music".
