Who do আপনি think inspires Justin too write his songs? Does he even write them দ্বারা himself, does he have help, does someone else write them for him?

Write your answer wether আপনি think Justin's songs come from him অথবা someone else writes them for him.
I personally think that he wrote them দ্বারা himself, because most of his songs are about girls and he maybe wants too fall in love.
