This page currently has songs by both the singer Josh Kaufman (pictured), a Tampa-based soul musician who appeared on The Voice, and the instrumentalist/producer Josh Kaufman, who is based in New York and contributes to indie folk/rock projects. The singer Josh Kaufman seems to have only put out songs under his own name, while the instrumentalist Josh Kaufman has only contributed to others' songs, so you should be able to tell which songs belong to which (although disambiguation of the artist pages would be useful).
