2011 compilation album by various artists
Allmusic reviewer Andy Kellman tells readers that while Now! 39 includes "hyper-energetic party songs" and two songs from solo male country artists (ending a three-volume drought), what is "notable is the absence of songs that could be squarely categorized as rap or R&B." He also points out of the bizarre repeat of "Tonight, Tonight" for the second volume in a row and the peculiar inclusion of "Bass Down Low" among the Now What's Next selections as it "hit the Hot 100 the last week of 2010".
