Manic Street Preachers are the latest in the series of artists who hide tracks on their album.
The hidden track is a song from British McCarthy who released a couple of albums by the late 80s and early 90s, Dotmusic reports.
The song is called "We Are All Bourgeoisie Now" and was originally recorded in 1987. According to the British Music Magazine, it is neither presented on Manics songs from the album "Know Your Enemy" or as part of promotion in relation to the press.
The man behind McCarthy, Tim Gane, has later become the brain behind Stereolab.
"Manics has contacted me about the use of the song, and gives us percentages if they sell some discs," says Gane to Dotmusic on Thursday.
"They have already made more cover songs of us. Among other things, "Charles Windsor", the page to "Life Becoming A Landslide". And I've made a remix of "Tsunami" for them, says Gane.
Gane has recently spent time in the studio in Chicago, where Stereolab has recorded his 12th album. About Manics he says: "I like what they have to say more than their music. I do not dig rock.
On Thursday evening, Manics played the biggest concert that has been held in Cuba for over 20 years.
"We respect the Cuban people and their traditions and would do a different concert this time," said guitarist Nicky Wire when the band arrived at Havana.
