Any art that comes from a real place is "palatable". Nevermind these major labels. Music doesn't belong to the labels. It belongs to the people.
Make it a habit to support artists that serve a higher purpose. Female mcs, underground djs, community theater, minority businesses, and non-profit orgs are all groups that need support from the people they work tirelessly to accurately and passionately represent.
Try everyday to listen to a new hip hop artist or new electro artist. Let your ipod be as diverse and unique as you are.
