Taylor Swift's "Shake It Off" was the publishing industry's undisputed champ in 2014's fourth quarter: The song helped lead Sony/ATV (which reps Swift) to its 10th consecutive leading quarter and Kobalt Music Group (home to co-writers Max Martin -- the quarter's top songsmith -- and Johan "Shellback" Schuster) to hold steady at a solid No. 2.

However, Sony/ATV's market share dropped to 26.2 percent from a third-quarter 31.2 percent. (The company also topped the country list with a 22.8 percent share, down from 26.9 percent.) Other big moves came from Big Machine and Reach Music, both of which hit the top 10 for the first time, powered by Maddie & Tae's "Girl in a Country Song" and Charli XCX's "Boom Clap," respectively.

In other moves, Warner/Chappell had the largest market share gain from the third quarter, growing to 13.27 percent from 10.91 percent; while Round Hill Music also makes its debut as the new owner of Big Loud Shirt catalog. In November, Round Hill Music acquired the Big Loud catalog and formed a joint-venture with Big Loud Shirt, which has appeared -- identified as Big Loud Bucks Administration & Information -- consecutively in the Top 10 rankings since the fourth quarter of 2012.
