Spotify的一項新研究顯示，“視窗”是指“視窗”是指延遲以特定格式或地點發行專輯和歌曲的做法，這可能會損害藝術家的成功。Spotify分析師仔細考察了梅根·特雷納的流行歌曲《關於那個低音的全部》在兩個市場的成功——在美國，歌曲出現在商店、流媒體服務和廣播上，同時也出現在電臺上，而這首歌首次在Spotify UK上市一個半月後才上市的英國。

The graphs representing the song's streams, sales, and Shazam tags are wildly different in shape. In the US, where fans could buy or stream the song from June 30th, we see a steady bell curve, rising to a peak in late August, before dipping slowly throughout Fall and into Winter. Shazam tags, which kept pace with the sales and streams, are a less concrete measure of success, but do show that the song was becoming increasingly ubiquitous, forcing people to turn to their phones to work out what they were hearing. The proportion of those people who were researching the song with aims of hearing it again would have been able to either buy or stream it on the spot.

In the UK, however, the rush of Shazam tags for "All About That Bass" peaked a week before the song was available in stores. The windowing meant anyone keen to legally acquire a copy of Trainor's song would have to stream it via a subscription service, try to maintain their interest for seven days, or simply watch it on YouTube, where it had been available worldwide since June 11th. Despite the month-and-a-half gap between US and UK releases, streaming figures for the song remained strong in Britain, showing a similar curve to the US graph and propelling Trainor into the UK singles charts on streams alone. But unlike the US figures, Trainor saw her song's sales dropped precipitously a few days after "All About That Bass" became available to buy in late September.

In the US, the song was available for stream and sale at the same time.

The Spotify study concludes that "the practice of windowing on any licensed platform — be it streaming or downloads — looks distinctly behind the curve." Releasing the song as a buyable product weeks after the most people are searching for it "leaves money on the table," as Spotify says, but it also gives people who can't wait for the official release time to discover and download pirate versi***. Of course, there's no guarantee those people would have bought a legitimate copy of Trainor's song, but huge fans might have had their hand forced with no other way to access an offline copy.

The answer — supported both by the Spotify's data and by c***umers sick of arbitrarily varied worldwide release windows — appears to be for media companies to realize that the internet is a global creation, and end the practice of windowing. But as Taylor Swift and other musical megastars assert their control over their catalogs, removing them from streaming services and attempting to enforce exclusives, it doesn't seem like record companies will be **ashing release windows just yet.
