Odd Future got hot in 09, Rocky in 11, they are far from new acts. If you wanna go back even more, Ross got hot in 09, Wale 11, Cole 11, etc etc Granted none are at the level of Drake but the rule exponentially applies, Drake's popularity will be sustained by all the dikkriding and hype mongering that goes on through social media. Rocky sold 100k first week, and Odd Future is extremely influential regardless of whether they're an "underground" group (which they are not mind you, underground rappers are ones 80% of rap fans have never heard of)
1-When I say new, I'm saying they haven't set any major steps in the game. In the music industry, Odd future is done. If you don't pop in 2-3 years, they stop dealing with you.
2-I see you are young, and have yet to see how people will turn on you like a snake biting your ass.
3-Rocky sold over 100,000 FIRST WEEK, yet it dropped significantly after that. You don't know why do you? If I tell you you still won't believe me, but it ain't no coincidence. First week is a pop music thing, most albums sell over time, not the first week. The album should be higher then the last, not less. To me that sounds like he lost fans.
4-Influential means nothing if no one knows you are the one influencing everyone. I seen tons of underground rappers start shyt, but no one knows but me, and other music heads.
