Can someone please tell me what I am supposed to do when playing this game at home?

Alright so I got this game in early 2024 but just recently reinstalled it and I got sucked back in but I have one question. What exactly do I do when sitting at home on this game because its raining so I’m not just going outside to collect songs and I don’t have enough coins to buy songs and nobody wants to trade w me. Idk if this is a dumb question I’m just trying to understand exactly what to do.
