A bar code reader, a wireless transceiver, an earphone jack and a battery are integrated into a pen sized device. The bar code reader is used to scan the product identification code or music packaging. The product code is sent to a central computer or a music store where one or more stored digital samples of the music reside in a database. One or more music samples are retrieved and sent to the pen sized device where the sample is converted to audio signals for listening by a user over the earphone jack.
