Attorneys in U.S. District Court in Boston gave opening statements Tuesday in the recording industry's lawsuit against 25-year-old Joel Tenenbaum of Providence, R.I.

Tenenbaum, represented by Harvard Law professor Charles Nesson, is accused of downloading and distributing thousands of songs, though the case focuses on 30.

Recording industry lawyer Tim Reynolds says song swappers such as Tenenbaum seriously damage music labels.

Tenenbaum is only the second music-downloading defendant to go to trial. Last month, a federal jury ruled a Minnesota woman must pay $1.92 million for copyright infringement.
