I do think Wale's frustration is that his career is not in the stratosphere that Cole's is. These dudes were opening up for Jay Z together a little over 10 years ago.
Which reminds of this video from that tour:
Also Cole opened up for Wale at one point on Wale's tour.
The thing I don't understand is that Cole went out of his way to help Wale very recently. He chilled with Wale for awhile, they wrote together, he was giving Wale advice etc...all this happened after the False Prophets shyt.
Wale mentioned it last time he was on the Breakfast Club if I remember correctly. For him to say some wild jealous shyt like this is just...weird man. What's wrong with this dude. He's never going to be as big as he thinks he should be. At this point all you can do is accept that your moment passed and make the best music you can. There's money to be made touring. Lot of hoes shyt fukk with Wale.
