has anyone else played the same song in the main street mix game 50 times (i am assuming 50 times when you get 25 credits) before? because it just gave me 375 credits for doing so.

It also gives you extra credits when you play your 100th mix. And when you play them on the monorail you get extra credits on your 50th and 100th times as well.

yup I done played mine so much I don't think they will ever give me credit for it lol. I think I went way over the 300th time at this point.

It's not playing the same song, it's playing any song. You get a reward for the 50th time you play any song of 375 credits and for the 100th time you get 750 credits. I'm not sure if they have more rewards.

After so many song plays you get bonus credits. I try to play when on VMK every hour.
