Lady Gaga has jokingly compared some of the tracks on 'Born This Way' to 'heroin'.

When discussing the eclectic sound of her forthcoming record, the singer said her first single, 'Born This Way', was like the drug 'cannabis' compared to the 'heroin' ' a much stronger and more dangerous drug ' of some of the other tracks.

She told Billboard.com: ', in jest, say that 'Born This Way' is the marijuana to the heroins of the album, the ultimate intense intoxication of the record. It's an analogy.

'On the album there's not an incredible amount of breadth and eccentricity. It's quite eclectic. It ranges from 'Born This Way' being very light to the rest of the album becoming quite darker.'

She also told how she feel the album's closing track, 'Marry The Night', embodies what she feels will be the sound of the future.

She added: 'One of my favourite songs on the album is the last song. It was originally going to be the first single. It's called "Marry the Night." It was produced by myself and Fernando Garibay. When Fernando and I did it, it was like this sonic light bulb went off and we were like, 'That's the sound! That's the future.'

'The record is just this massive, gas-station, disco record, music - that every single one of these songs could have been a hit record.'

'Born This Way' is released on May 23.
