Just to expand on this, it would be nice to be able to select the key + harmonic keys (I have smart crates for this) and a BPM range that would be within +/- 8 or whatever your hardware supports.

What we need is an over arching bpm range filter for the library/crate. It could even be updated by the bpm of the playing track.
That way no mater how else you wish to order/sort out your list it will always be of a mixable speed.
It would be nice to have an over arching Key range as well but not as usable for everyone as a bpm range.

+1 but to me I would chose "key + iTunes rating"

There is a workaround but it requires time sorting it manually.....by placing your tracks in the order you want in the prepare window and putting a number in the comments tag or any available empty tag your not going to use. Then just click on the tag whenever you want to sort tracks in that order.

I see the new Beatport Pro has a couple of choosable filter preferences above their library window. That way you can choose via 2 or 3 drop down menus what you want to filter your library by. And those 2 or 3 menus are customizable with options such as BPM range, Key, Genre... and so on.
That's a large amount of customizability for filtering and would be amazing and incredibly useful for every dj.
My largest issue with Serato, compared to Traktor, is search-ability. The fact that I've had to make 'BPM range' smart playlists as a work around to be able to simply search for tracks that are within the same BPM range. It seems silly that I need a work around for such a obvious part of dj'ing.

I've just started a filter library by BPM post which will hopefully get some attention. If anyone here is interested or wants to add to it they can here serato.com
