​We're looking back on the best music of 2015. Our editors have compiled lists of their favorite albums of the year from over 20 genres, and we'll be releasing one list a day as we get closer to New Year's. And we'll be tallying your votes for our annual readers' poll -- find out how to make sure your favorite albums make the ballot.

We started with the list of best overall albums of the year, then dug into the finest in rap and hip-hop. Check back every day over the next three weeks for a new list.
