How about us (me too) are still as beginners, if want to create a good song, and hopes to be hit?
certainly not an easy matter. because the process of creating a song is not limited only to create the course, without a what must be done after that. is the path to the music's industry indeed.
In fact there is no rule that requires that a song that should be created like this or that. because it creates a song or whatever is the process of creativity. so that flow is not, and can be sets. but for this, we must follow the rules of the music/songs that can be accepted by all sections of the community music lovers, if the aim is for a commercial. if we want to idealist with music. song in accordance with its own character and passion, we want to make up a song ... well I also like music this is indicated by an indie band/singer. free expression, exploration, and improvisation in accordance with the character you want indicated.
For a musician, can create a song is a solitary satisfaction. because indeed, commercial purposes is not the final destination for "true" musicians. can be popular and a lot of money is the result of hard work of creativity that deserves obtained. because the musicians only wanted to create a song to entertain other people and, "Himself."
