For decades, major record labels have had significant power when it comes to how they market. Bound by contracts, acts mostly abide by what their label tells them to do. There are plenty of acts who also have say in what they sing or write or wear. However, the singer-songwriter era of music is behind us. It is rare to hear about singers writing their own songs as nowadays' market is based on mostly formula compositions, or songs that have a specific way they're written and the sounds usually end up being recycled.
