You've known Silver for a while now, so you're aware of the slight personality changes he's undergoing. Not that he's completely changed, but he's finally able to have fun and express himself like a normal teenager.

That said, Silver told Ethan he wanted to try new things besides battles. That's when Ethan suggested he start an emo band, since, from the looks of it, Silver would do well in one. Ethan's words!

And that's why Silver came to you. He liked the idea, and you're one of the few people who plays an instrument Silver knows. More than that, one he actually tolerates.

"Join my emo band!" he said to you, seriously determined. Coming from him, it sounded oddly comical in a cute way.
