As packing shapes is always a problem with a high complexity I needed to come up with a solution that is also fast.

The main reason is that last.fm limits the number of requests to their services to 5 requests per second. While this is perfectly understandable it also means that this number of requests has to be shared among all users that are using the Tools. Sometimes the computation of a single method like the Soulmates needs heaps of calls in order to be completed.
