Florida Georgia Line

This week on the Billboard 200 albums chart, the "Now 50" album spoiled the "Frozen" party, as the former debuted at No. 1 with 153,000 sold in the week ending May 11, according to Nielsen SoundScan. The "Frozen" soundtrack slipped to No. 2 after 13 nonconsecutive weeks at No. 1.

Outside the top 10, there were a number of movers and shakers -- let's take a closer look at some of them:

-- Florida Georgia Line, "Here's to the Good Times" - No. 11 - After 75 weeks on the chart, the album shows no signs of slowing down. This week it climbs 14-11 with 17,000 sold -- up 33 percent. It has yet to rank below No. 31, nor sell less than 12,000 copies in a week. Its cumulative sales stand at 1.82 million.

The duo's current single, "This Is How We Roll," rises 4-2 on the Country Airplay chart, while dipping 3-2 on the Hot Country Songs chart (where it previously spent four weeks at No. 1).
