Information about desired songs is collected on a portable memory device in communication with a radio tuner. The radio tuner may receive signals from a terrestrial or satellite digital radio transmission, or from an analog radio transmission. These transmissions may include text data about the current song being played. Upon activation by a user, song data is stored on the memory device. The memory device is then connected to a computer system, which uses software to extract the song data and uniquely identify the song. The identified songs are stored on the computer system, and can be used to allow the user easy access to the identified song through prior art techniques. If no textual data is stored about a song, the song is identified by identifying the radio station that played the song and the time at which the user activated the mechanism. |
