The present invention relates to a music identification/purchasing system, specifically to a method for marking the time and the name of the radio station in portable device such as a key holder, watch, cellular phone, beeper or the like which will allow the user to learn via internet or regular telephone the name of the song, artist and/or music company by matching the stored data with broadcast archive. The system will allow for purchase of the full length of the identified music item or related music. An alternate embodiment provides the listener with convenient means to record a segment of the music in which he/she is interested. The recorded music segment is played back into an apparatus which can identify the song based on the play back and provide the user with information on the identified song such as title, singer or artist, composer, producer, etc., and provide related purchasing information. The user can make selections and provide payment data to the music identification/purchasing system which will result in the selections being delivered to the user by mail.
