Not noticeable with current database size, but lays a good foundation for larger libraries. For example, given a list of 300 artist IDs, checking if an ID is in the list takes between 30 and 40 ms (for an ID towards the end of the list), while the MapSet version takes consistently between 15 and 20 ms.
