Customising PerfectPitch Ratings

Why should I change the ratings?
To reflect more accurately your local dance conditions. Many of the songs that are highly rated appear to be popular across a wide geographical area and audience. Others are popular locally, for example "Londres" by Luis Felipe was popular in London for a while but appeared to have little impact elsewhere.

Fine-tuning PP helps you out when you're in a jam. A well-adapted system acts as a guide through rough patches during DJing, like when suffering a mental block or a lack of inspiration.

How do I go about changing them?
Identify the difference between PP and the preferences of your local group.
Listen for songs that are popular locally, then compare and convert their ratings on PP. Convert the remaining ratings, beginning with the accessible music, from the top down i.e. three rated, two, one, then zeros. Once you start, you'll need to keep developing a feel for the sort of music your guests prefer. You should substitute your own ratings, even changing the scale to a broader one e.g. 0-5 to give you more flexibility.

If I know the music that well, why bother with the rating system?
The larger your collection gets, the more difficult it becomes to keep track of the good songs. The advantage of relying on memory is in the speed of selection, but you can end up settling into repetitive and predictable patterns. Having a reliable system secondary to your memory can help prevent your DJing from stagnating.

Why weren't the ratings on a 0-5 scale in the first place?
This version is designed for training. Trainees find the smaller rating scale psychologically less daunting at 0-3, and the inherent lack of resolution encourages them to explore the music and make up their own minds.
