@Brandon > There is not one set BPM range that would apply to any of these. It would have to depend on the particular track you're analyzing. For example... The acapella of Uptown Funk would be 115 BPM while the acapella for In Da Club by 50 Cent would be 90 BPM. You need to select the appropriate range for each track/group of tracks you analyze regardless of whether it's a full song, instrumental, acapella or loop.
If you're just playing back a one-shot, then this doesn't apply. There technically is no BPM on a one-shot.
