An Atlanta music streaming service that promotes itself as “the 800-pound gorilla of free hip-hop mixtapes” contends that, when the nation’s largest recording companies sued it for $3 billion last month, they omitted a key detail: that the recording giants had asked Spinrilla to promote and distribute their music.

Spinrilla and founder Jeffery Dylan Copeland also claim in a formal answer to a copyright suit in federal court in Atlanta that they “have been cooperating for years in a variety of ways” with the major recording labels to remove any unauthorized music that might constitute copyright infringement.
