Curb Records is suing Tim McGraw. Again.

The Nashville, Tenn.-based label has filed a lawsuit against the country music star and Big Machine Records in federal court, alleging copyright infringement and breach of contract.

Curb has also sued McGraw in Tennessee state court, but has thus far failed to keep McGraw from recording new music under a new agreement with Big Machine, which put out "Two Lanes of Freedom" earlier this year.

The lawsuit asks for a return of master recordings, compensatory and punitive damages and an injunction against future recording or releases until its contract with McGraw has been fulfilled. The state case remains in front of a judge, but the court allowed McGraw to record for a new label in a decision that's been upheld on appeal.
