You're naming a few, and the change started in 1997. Before that there wasn't much love for artist from other regions like that. I remember the source shytting on a lot of southern, and west coast artist, funkmasterflex dissing west coast, and mack 10 coming for his ass. Why do you think the westside connection was formed, and the disses they had were about? Outkast, and goodie mob complaining on the radio about being booed at the New Music Seminar in 1993/1994, and the source awards, scarface talked about the ghetto boys being booed at the same seminar in the early '90's.
From what I remember, NYC only liked artist when the artist became big all over the country, and went "pop", but when they were popping on a smaller level, they got no love for the most part. Yeah some liked them, but the average didn't, UNTIL that southern sound started gaining props. From what I can tell it wasn't like that in some of the south until we started hating so much, and definitely not on the west coast.
An example is tag teams "whoop there is it" that you gave. I remember that song being a hit all throughout the south before NYC even thought of playing it, once it started gaining notoriety, then I heard it on the radio. Another is luke, like you gave. His hit with "I wanna rock" got play in NYC when it came out, but luke was bumping before that, and after that, but no love in NYC. "Scarred" was the shyt, but NYC wasn't playing it. Same for "raise the roof". shyt when 2 live crew was selling platinum, you didn't really hear their songs on the mixshows on kiss or wbls.
Yeah, NYC started giving love in the late 90's, but it was too late, and even then they were still hating on the low. Remember in the mid 2000's when the south started really gaining in popularity, particularly Atlanta, and people
.....
were hating on the south talking about how they were going to "bring NYC back"

. You think the south didn't take offense to that?. Even Ludacris rocked a shirt stating "Hip Hop isn't dead, it lives in the south" at the B.E.T. Hip Hop awards when Nas came out with "Hip Hop is dead". I agree with both of them actually. Nas meant the culture of Hip Hop, and Ludacris meant the music making money, and growing.
Ice Cube let it be known on this shyt:
