I think the sound you’re hearing is a sampled bass drum sound triggered by the conga player (odd combination huh?). You’re not crazy, I have to agree with you, it’s annoying, out of place and it kills the mood of the song.
I suggest you to calibrate the sub level, it’s possible that you have too much juice on the sub, and that will make it worse than it is.
I have to admit , your post was kinda amusing, I’d always thought the same but didn’t have the nerve to say it... :P
