13. A device for identifying an audio content sample, comprising: a processor; a computer-readable storage medium storing instructions, the instructions which when executed by the processor cause the processor to: monitor a plurality of broadcast stations, fingerprint and save the fingerprints of broadcast audio content in a database of unidentified broadcast content as it is received; access playlists, comprising portions of identified broadcast audio content from the plurality of monitored broadcast stations, and fingerprints corresponding to the identified broadcast audio content; receive data representing sampled audio content from a portable device and search for a match between fingerprints of the sampled audio content and the fingerprints corresponding to at least parts of multiple playlists, further including: upon finding a fingerprint match against the fingerprints corresponding to a particular playlist for a particular monitored broadcast station, report the particular monitored broadcast station as a source of the sampled audio content, and identification of the sampled audio content back to the portable device; and upon not finding a fingerprint match against the fingerprints corresponding to the multiple playlists, further search for a match the fingerprints of sampled audio content, against at least one of: parts of the database of unidentified broadcast content from the monitored broadcast stations, to identify a source of the sampled audio content; and a reference database of identified audio content not associated with a particular broadcast station, to identify the sampled audio content; and report back to the portable device at least one of the source of the sampled audio content and the identity of the sampled audio content.

The device of claim 13 , wherein the non-transitory computer-readable storage medium further includes instructions, which when executed by the processor, cause the processor to: receive a location from the portable device; and use at least the location and the identified sampled audio content to target the portable device for advertising or offers.
