I have analyzed my entire library using range as automatic....the BPM for the entire library has a resulting range of 60 to 140.....as an experiment I changed the range to a defined range of 110 to 220.....and later from 200 to 400.....and analyzed a small section of library.....each time I got BPM ranges higher and in the new range....I then went back to automatic....and the BPM went back to the original result between 60 and 140....
So?????.....What is the correct BPM?....The one from automatic\?....The one from each of the arbitrary ranges?????
Can you explain????

    For BPM algorithms it is hard to distinguish between 60 and 120 BPM. Or 70 and 140 BPM. They just look very similar.. Therefore beaTunes allows you to preset a range that you expect the true value to be in. 70-140 is usually a very good guess.

    That answer is no help......
     
    Can I set the range to be broad....like 60 to 500.....and then analyze the
    whole library?
     
    My library is 75000 songs/tracks.....I DO NOT want to go estimating the
    range for each song one at a time.....that will take years.....

    If you look at the possible BPM ranges, you will notice that you can't set the range to 60-500. With beaTunes your best bet is currently to simply select 70-140 and accept that some songs may be slower or faster and therefore not correctly labeled. I hope to improve the situation in the next major update, but for now that's unfortunately the best it's got to offer. That said - you will cover most music with that range.
