There are definitely exceptions for live performances.
At Emmis' Mega 98.3 in Buenos Aires, a classic Argentine rock station, we had "Megaacoustics" on average twice a week in the 11:30 to 12 Noon period. Short set, usually 5 to 7 songs, acoustic, and a limit of one song from the "new album" to avoid stiffs.
It was promoted several days in advance each time, and the ratings spiked in that hour always.
Artists were invited to participate (an idea I stole from the Grand Ole Opry) and we only picked superstars. They were the local equivalents of everyone from Jefferson Airplane to U2 (we covered five decades of Argentine rock and promoted that fact).
Fortunately, we had a "green room" that we set up with all the proper mikes and gear for these shows, and the room had the right acoustic treatment.
The success was having only the biggest superstars... the A list of the format... on the shows. Most of the artists allowed and signed releases for recording and use at later times of the songs played on the show. We put a number of acoustic cuts in the programming on Sunday evening, extending the impact.
This contrasts with our attempt to do a new talent show on Sunday evenings, playing recordings of unreleased artists from the market or first release new artists. That dug a hole in the Sunday numbers that you could have hidden the Obelisk in so we stopped that quickly and started playing our growing collection of recordings of the live acoustic songs by big artists.
