1. A method of categorizing resources on the Internet, which provide streamable audio content, the method comprising:

searching the World Wide Web of resources for resources which provide streamable audio content;

identifying a specific one of the resources, which provides streamable audio content;

analyzing the audio content of the specific resource according to one or more predetermined criteria; and

,

indexing the specific resource to one or more particular ones of multiple categories based on the analyzing.

2. The method of claim 1, wherein the analyzing of the type comprises analyzing (106) an URJL of the specific resource.

3. The method of claim 1, wherein the analyzing of the type comprises analyzing an HTTP header of the specific resource.

4. The method of claim 1, wherein at least one criterion is associated with a particular natural language of the content (216).

6. A method of locating at least a specific one of multiple Internet resources (212;

213) that provide strearnable audio content, the locating comprising;

supplying input information representative of the specific audio content to a search engine (226);

requesting the search engine to query a data base (222), consisting of a searchable collection of streamable audio documents associated with the Internet resources, based on the input information supplied;

if the search engine finds one or more matching ones among the documents, receiving one or more hyperlinks (214) associated with the matching.

7. The method of claim 6, wherein the supplying comprises providing textual information to the search engine.

the search engine is coupled to an input (308) for receiving the input information representative of an input sequence of input musical components;

the search engine is operative to identify one or more particular bibliographic information items upon finding a match between one or more reference data and the input information; and

the locating comprises finding a match between the one or more particular bibliographic information items and one or more of the audio documents.

10. A method of enabling to identify a specific one of multiple resources on the Internet that supply streamable audio, the enabling comprising:

providing a searchable data base comprising hyperlinks representative of an indexed collection of the resources;

providing a search engine for querying the data base upon a user having submitted a query item; and

providing at least one of the hyperlinks upon the search engine finding a match between the query item and the data base.
