BPM & Chords Live Analyzer - DJ and Musicians Tool

I noticed that some of my songs in my music library were analyzed correctly like ASHITAGA ARUSA, but some were analyzed wrong (for instance, Saitama 2000 being analyzed as 159.97 BPM when it was actually 200 BPM). This needs to be updated immediately!

Just analyzed a song that was 101 BPM and this all said it was 179.9. Even worse it said the chords were B major and G# minor... neither chords exist in this song. How do I get a refund?

I got this app to analyze 19 chords coming from my DAW that were played on a synthesizer (in unison, not arpeggiated). I wrote down the app's results for each, then tested on a keyboard. It got all of them right. I was quite surprised. The synthesizer sounds were little bit muddy so I imagine the app does fine with more clearer material.
