Reply to record pools/serato question

Hey guys I'm part of 2 records pools djcity.com and franchiserecordpool.com. Both these sites are great. My question is these sites say that they have bpms and overviews already tagged in the mp3 for serato, so is there any sites that support Traktor in the same way? Or if the bpm is already tagged for serato will Traktor detect it as well? Traktor is great but the time I spend on beatgrids is brutal.
