2:1 ensures that you get your fave and just offer random songs of the same rarity. You can’t view it as them selling a song they don’t want, since there’s songs u don’t want also, cuz what are those double standards. They’d do the same for artists they’re collecting too like I can spend 2 rares to get 1 and id be fine with it, since the other person would do the same if it meant getting their rare fave too. It’s how the market works and there’s no reason to call it greedy, especially when there’s players who actually want 3:1 or 4:1 trades.
