How I Can Use Garage Band Later

I can use Garage Band later on in life when I hear a song that I think would sound better with a different beat. I can edit, change, or better a song or even create my own song. I can use Garage Band even if I enter a contest, like the Shamaley Chime and Rhyme Contest here in El Paso where you make a jingle including Shamaley plus the word(s) Ford, Buick, or GMC. Making a good enough jingle could get you some money. And who knows, Garage Band can even start someone off as a rapper or singer.
