Big Sean just had a major setback for his major comeback … hackers leaked the foundations for his new album … and claimed they did it to avenge Kanye West!!!

If you recall, Sean recently set the record straight against DJ Akademiks‘ allegations that he was dissing Kendrick Lamar  … further clarified by DJ Hed that Sean’s shots were actually reserved for Kanye!!!

Shortly after, a collection of tracks titled “Feelings & Random Thots” featuring artists such as Nas, Hit-Boy and The-Dream was planted on message boards … along with the cryptic message that it was middle fingers to him and the entire team!!!

Early this morning, Sean hopped on IG Live and admitted the leak crushed his soul a bit … the songs were just templates and experiments and he felt a little exposed having that in the public’s eye.

Sean wouldn’t buy into the hype that Ye was responsible, however … he sold MILLIONS of records underneath the Good Music umbrella — their history is deep-rooted!!!
