KeepingDJ collection separate

The advice from DDJT has always been to have two totally separate collections. Your DJ stuff in one, all the rest in the other. Luckily it is very easy to start iTunes with an option to create/use alternate collections. By determining where you keep your music yourself (rather than letting iTunes move your tracks to a default place) you should keep at least your DJ tracks in an easy to find/manage place.
