Should I be Worried?

Should I be worried? Little-D starts to sing but he changed all the lyrics. A good song become a bad song as he changed almost everything and he sang it like shouting! Do you think I should send him to some music school for toddler? As for now, we have yet to send him to pre-school yet as I am planning to send him to some mandarin class at baobei first and see how he is progressing. Should I? Should I not? Music school will be a good choice? Maybe I should go and check out some of the music school around the area and at the same time get the Ernie Ball guitar strings for my cousin.
