On the volatile Billboard album chart these days, one week you can be No. 1, and the next you drop to No. 169.

Case in point: Bon Jovi’s “This House Is Not for Sale.” The album, which came out almost a year and a half ago, returned from oblivion last week to reach No. 1, thanks to a deal that bundled the CD with the cost of concert tickets for Bon Jovi’s latest tour.

Such deals have become the music industry’s favorite new sales gimmick, used by everyone from Metallica and Arcade Fire to Pink. And since chart positions are now computed by looking at both sales and streams — with sales of full albums given the most weight by far — a well-timed ticket bundle can be a quick path to No. 1. This practice has raised concerns, but Nielsen denies any chart manipulation.

Bon Jovi’s 168-spot plunge, however, is the biggest drop for a No. 1 album in the six-decade history of the chart, according to Billboard. (The previous record-holder was the emo band Brand New, whose album “Science Fiction” fell 96 spots last September.)
