7. A system comprising: one or more processors; and one or more memories storing instructions that are executable by the one or more processors to perform operations including: receiving, from a device, a first query including one or more features extracted from audio data captured by the device, each of the one or more features comprising at least spectral peak data associated with the audio data; processing the first query effective to attempt to identify a song associated with the audio data; receiving, from the device and independent of a prompt for a query, at least one additional query including at least one of the one or more features included in the first query and additional features extracted from additional audio data captured by the device that were not included in the first query, the additional features including spectral peak data associated with the additional audio data; processing the at least one additional query effective to attempt to identify the song associated with the additional audio data by: scanning a content database across a first beam width corresponding to a frequency range to produce one or more content item candidates having peak information corresponding to the spectral peak data of the at least one additional query; and scanning the one or more content item candidates across a second beam width to produce a content item candidate with peak information corresponding to the spectral peak data of the first query and the at least one additional query; identifying the song as the content item candidate corresponding to the first query and the at least one additional query; and responsive to identifying the song, returning content information associated with the song to the device.

The system of claim 7 , wherein the second beam width is wider than the first beam width.
