Creating Quick Clustering Algorithm

Decided to use a clustering algorithm for my data, since music will be
grouped into categories. These categories can then be given names to
represent eras. Currently, this may not provide accurate results with
current data, however only key points of data will have to be added to
give a more accurate result. The example I'm working on will help
produce a good starting algorithm, and give me an idea of how to work
with multiple dimensions.
