That was also a different time in hip-hip because they all hung out together - artists and producers - so you can't parse out who showed who what, but Preem always drops Marley's name when talking about greatest producers.....as well as Dre though, so I wouldn't necessarily place one above the other and a good argument could be made for either one.
