[1] This practise takes advantage of a 'release window';[1] it occurs when an upcoming song receives much airplay despite not yet having been released.
[4] For example, UK number one "Talk Dirty" by Jason Derulo featuring 2 Chainz,[5] made No.
was intended to be released on 8 September 2013[9] however on 15 July 2013 the Official Charts Company announced that it would be released that week[10] after a group called Spark Productions recorded a pre-release cover version and made No.
While the practice is legal,[3] the area of licensing they are operating in has been described by PRS for Music as "tricky".
[15] Barney Hooper from PRS for Music said that along with record labels and publishers the trend was something they were "investigating" and "thinking about a bit more".
