Strange failure by ACR

Tonight (Friday 1/29/21, 6:00-7:00 PM) my DJ devoted his soul music show to playing two versions of the same song. Oddly, even though the two versions were sonically and stylistically different, ACR only recognized ONE of each pair. (For example, he played George Benson’s version of On Broadway and the original Drifters version of On Broadway, yet ACR only recognized the George Benson version – even tho the Drifters version is a popular song). Can you report this to the ACR folks?

Hi Steve, this is Peng from ACRCloud. Thanks for letting us know about this issue. We do have both versions included in our database and I tried to recognize each version and it works.

So the only way to find out why it happened is to check the audio played at that time. Is this something you can provide?
