MGMT's collaboration with Jay-Z was rejected because they "went crazy".

The psychedelic pop duo admit they took the wrong approach to the track sent to them to work on by the rap mogul for his last album 'The Blueprint 3' - and it was subsequently rejected.

Band member Andrew VanWyngarden said: "We were under the impression they wanted us to go crazy."

The duo - which is completed by Ben Goldwasser - has come under fire recently for their second album 'Congratulations' not including any pop hits, akin to the songs which made them famous, including 'Kids' and 'Time To Pretend' - but they feel those songs were nothing revolutionary.

Andrew added: "We used to think about how to make the most stereotypical pop song and that's the ones we did. You can break it down. That repeating progression has been used in a gajillion pop songs."

MGMT also claim their stance on music is widely misunderstood, but have done little to help their own image.

Andrew said: "We were portrayed in a lot of articles as these partying-obsessed dance music fanatics. Which we thought was funny at first, and then we realised not many people understood what we are really trying to do."
