Is Lukas a new artist? Never heard of this guy until 3 weeks ago
It's a band from Danmark. They released debut album in U.S. and Europe at the end of the march but in Danmark they had 3 studio albums, and apparently all them were called "Lukas Graham"
Disturbed TSOS is #13 & #288 right now. The version at #13 is at 0.44055 (also #1 on Rock), and the version at #288 is at 8.56933% of the original. So I multiply 0.44055 by 1.085693 and I get 0.47699. Because of the gap between Disturbed and Grande, combining the two versions doesn't help TSOS move up in rankings here.
