Heavy is currently #32 on US iTunes but it is rising, so It should be back inside the top 30 shortly. Heavy has been on one hell of a rollercoaster; It's a tough little song that isn't quite giving up yet. Heavy is #16 on the Billboard Pop chart, making it their biggest hit on that chart in 9 years. It is #16 on the Billboard Adult Pop chart, as well, and #3 on Billboard's Hot Rock songs. The one place where the song is struggling is on Spotify. Heavy is currently not even in the top 200 in streams in the US. It needs a lot more streams; hence, why it's ranking on the Hot 100 is still somewhat low compared with it's other stats. In all other areas, it's kicking ass for the most part.
