When you are at a party usually there is just one person connected to the speaker. And after they finish their playlist usually people like to themselves play a couple of songs of their own from the same phone because that phone is already connected to the speaker. And if the person whose phone it is maybe doesn't listen to the same music as the other person playing songs from their account. My idea is you should add PARTY MODE or something like that where you can play any song without affecting your algorithm in the future. So you would enter that mode when someone else is playing music from your phone (account) that you usually don't listen to, so it doesn't affect you when the party is over. I expect to see my idea in the next update!
