devices. Broadcast, soundtrack and streaming When a recording is broadcast (either on radio or by a background music service such as Muzak), performance rights organisations (such as the ASCAP and BMI in the US, SOCAN in Canada, or MCPS and PRS in the UK), collect a third type of royalty known as a performance royalty, which is paid to songwriters, composers and recording artists. This royalty is typically much smaller than publishing or mechanical royalties. Within the past decade, more than "15 to 30 percent" of tracks on streaming services are unidentified with a specific artist.

However, in the 21st century, it has become more common to release recordings to promote ticket sales for live shows, rather than book tours to promote the sales of recordings. Major, successful artists will usually employ a road crew: a semi-permanent touring organization that travels with the artist during concert series. The road crew is headed by a tour manager.
