Just out of curiosity:

I used to trust [Mixmeister BPM Analyzer](http://mixmeister.com/bpmanalyzer/bpmanalyzer.asp) for calculating BPM values (okay, it sometimes doubles/halves, but wth). Now I ran across a tool apparently many DJs trust for harmonic mixing: [mixshare’s »Rapid Evolution 2«](http://www.mixshare.com/software.html) which in most cases gives a totally different reading. (What I like with RE2 is that it tries to find both key and time the song was written in.)

Would any _musicians_ or _professional DJs_ care to try these out and let us know which one is »right«? I myself am pretty much ignorant about music theory but still would like to have _correct data_ in my music database, so I’d like this question to be answered by some professionals.

Thanks in advance.

I've noticed that - but Rapid Evolution is so very slow (Java) - so I don't use it.

I'm using the very fast MixMaster BPM Analyzer - but rounding to one decimal.

I'm with you - I like correct data.

But try to check it on Pioneer CDJ 1000 MK3 or 800 MK2 - different BPM's too.

.. and .. I've just did the run over all 70's records .. which BPM should I use from e.g. Carwash? First minute 113, 2nd minute 121 .. 😉
