TAG, THEY'RE IT: Kendrick Lamar's Isley-sampling "i" makes a colossal 181-place jump on the Shazam USA Top 100 Tags Chart this week, while indie kids Ages and Ages blow up with "Divisionary." Nico & Vinz also earn a huge welcome for their new hit. Other big gainers include Sam Smith, whose "I'm Not the Only One" jumps #93-56 and Eminem f/Sia's "Guts Over Fear." See the whole chart, sortabe by artist, rank and biggest gainers, here. Kendrick also made a big leap (and Meghan Trainor is also #1) on the U.K. rundown, which you'll find here. (9/30p)
