2015 was a pretty phenomenal year for music. After the relatively dry 2014, we thought it was a drought, but the overwhelming amount of material made making our year-end list both very easy and very difficult. On one hand, there was a wealth of album to choose from, but on the other hand, a lot of great stuff had to be left on the cutting room floor. 

Not only was there a great volume of music in 2015, but also a lot of variety. This list season has seen arguments between different generations of rap fans, mainly because there have been strong showings from traditionalists as well as from exciting new songwriters. Atlanta and the West Coast both had their share of big voices, as did Chicago. It's also been a year where rap and R&B have had more crossover than ever, and the presence of singers on the list is a good indication.

What's your pick for number one?
