30. Audio Query Scenario
1. The user sends a sample of a song to the server.
2. The server replies that it has 100 possible matches for the song since the
example provided by the user was not of sufficient length or contains
noise.
3. The client asks the server what is the genres ( types ) contained in the
result set using an FRU query.
4. The server replies using FUU: rock, country and classical.
5. The user sends an additional query term using FRU: the genre is country.
6. The server finds exactly one match for the given criteria.
