[Shane H]

I have a question about the 7 on 7 acheivment. Do you have to have 7 exp on a playlist? Also October 7th is coming up in like 2 days and if i have 7 exp on a playlist and i play that playlist on that day will i get the acheivment? Thanks

yes, its very simple. play the playlist until you reach 7 exp on that play list. The achievement will automatically pop up when you are done.
