Oasis are due to release a new album later in the year
Three previously unheard recordings by Oasis have been leaked onto the internet.
The songs - I Wanna Live In A Dream In My Record Machine, Nothing On Me and Stop The Clocks - have appeared on a number of different websites.
A spokesperson for the band said the leaked songs were "old".
The BBC understands the tracks will not necessarily appear on the band's seventh studio album, due out later in the year.
Last year, lead singer Noel Gallagher told music magazine NME that the song, I Wanna Live In A Dream In My Record Machine, was "about buying records" and was "kind of like a Champagne Supernova thing".
The song Stop The Clocks, which was also the name of the band's 2006 greatest hits compilation, was considered for inclusion on their last studio album, 2005's Don't Believe The Truth.
Last month, Gallagher criticised the decision to have rapper Jay-Z headlining this year's Glastonbury Festival.
"Glastonbury has a tradition of guitar music and even when they throw the odd curve ball in on a Sunday night you go 'Kylie Minogue?'
"I don't know about it. But I'm not having hip-hop at Glastonbury. It's wrong."
Oasis are the latest in a long line of artists to have tracks leaked onto the internet.
