3 idiots is the one of the best movie of aamir khan .all songs in this film was very good, specially kaha se aaya tha vo, that was my favourite song .in this film one thing is most important, that is don`t memories the topics try to learn the lession .which gives a strong message.this song escapes me in another world.This film shows that aamir khan is really mr perfectionist who makes film with great script
