>>16815609I'm reluctant to bite on a tribalfag bait, but whatever. There are two major music industry players in Asia: UMJ and SME. Cover's networking with both companies is evidently severely lacking, in part because they started later than Nijisanji. Anykara/Ichikara was quick to snag tasty contracts with both companies, so they have access to great producers - getting Teddyloid to write a song for EN 2 debut is no mean feat. Cover resorts on outsourcing songs to less skilled but more affortable producers.
With that said, while Nijisanji is easily the best agency music wise (not just quality, but quantity too
