i dont know d browns (nor t browns) "baby dont do it" but if it has lyrics like
baby dont do it
dont you break my heart
oh baby dont do it
dont break my heart
my biggest mistake was loving you too much
then its not an original d brown song, im not sure who wrote it but it may have been marvin gaye or at least him singing it. i know the band (dylans band) did a cracker version of it on, i think, the album rock of ages.
