Mix it up, as in play the songs in a different order? Sure that'll help, but even if you watch the same five movies in a random order every night, it's still the same five movies.
Though 6 hours worth of songs and 6 hours worth of movies are different, you can probably get more enjoyment out of the songs, but the concept still applies.
Also I'm in a really bad mood right now, because people have really stupid logic. I was playing with a 'troll' who was cheating, but it was okay because the cheating was similar to an in-game mechanic. A game mechanic is literally a part of the game, put in by developers. Cheating is not part of the game, and when the rules specifically call something out as cheating, it's not meant to be done. Another guy didn't care about the cheating, because it didn't do anything to him. I said 'troll' because, while she claimed to be one, and she was surely acting like one, she was also defending herself honestly. You can't use the fact that you're trolling as an excuse for stupidity. They were cheating with their "boyfriend," but from how they were acting, I'm inclined to believe they're the kind of "couple" you'd see in elementary/middle school, I.e. something along the lines of, "Hey, do you want to go out?"
"Oh, sure."
"Okay, text you later."
"Kay."
And then they proceed to act like it never happened, but yet they're "dating." Like, sorry to spoil the mood guys, but that's not dating. There are random strangers who are less cold than you two are to each other. Dating isn't just a status on social media, it actually means something.
I don't get how people can have moral compasses this skewed. I mean, I know there are much worse people irl, but if you don't want to follow the rules, then just don't play the game. You can't say that about life. If you don't follow the rules in life, you either succeed greatly, or get punished severely.
Also I know I'm taking this a bit seriously, but I'm tired of people breaking the rules and saying, "lol its just a game dude chill," because if it's JUST a game, then go play another game, after all, they're both JUST games. It's not like you play a certain one because you WANT to play THIS game. When you cheat, you might have more fun than if you weren't, but that's usually a sign of you playing a game that's not meant for you.
Tl;dr: Even if you put your songs on shuffle, it'll get repetitive quickly, and people suck.
