An arrangement for providing and licensing for use a dataset comprising a musical accompaniment soundtrack is disclosed. The dataset is forwarded to a musical accompaniment unit over a data routing network. The musical accompaniment unit then seeks a license for use of the dataset from a transaction server, and stores a license code allowing the dataset to be used only on that unit. The unit is adapted to play an accompaniment soundtrack from the dataset and to simultaneously record and store one or m ore soundtracks. These can be mixed with the accompaniment soundtracks as required. The dataset may also comprise images, musical notation, lyrics and other supporting material. |
