Features
What is a Feature?
A feature is when one artist creates a song with another artist that not only builds cross promotion but changes the sound of each individual artists musical branding.
How many features should I do?
In general an Artist should do features as much as possible, not just for musical advantage but the personal advantage of challenging one self. Professionally an artist should have 3-5 feartures per album given the album is 10-12 tracks long.
