Got to give The Observer a fair bit of credit for this as when it appeared in late 2003, The Strokes were one of the hottest acts in the UK.
It was there to promote the release of the band’s second LP Room On Fire and the five tracks were:-
mp3 : The Strokes – When It Started
mp3 : The Strokes – New York City Cops (live in Iceland 2002)
mp3 : The Strokes – Last Nite (original demo)
mp3 : The Strokes – Meet Me In The Bathroom (Home Recording)
mp3 : The Strokes – 12:51
The first track was a b-side to Last Nite while the last track was taken from the album the sampler was promoting.
I think the paper cost £1.50 at the time so picking it up for the three otherwise unavailable tracks was worth it.
Enjoy.
THE NEW VINYL VILLAIN 
Like seemingly everyone else, I fell for these guys in a big way in 2001, but I must have missed When It Started. Thanks for posting.
Maybe someday I will figure out what all the fuss was about with The Strokes…
Try starting with Someday… It’s a great track 🙂
