Well this is proably old new to you brits, but since im canadian its new to me.

On the iTunes music store they have those artist essentials packages, like greatest hits or songs to get you into a band. So in the canadian music store they dont have them, but i read about them in a newspaper. so i saw them on the american store and they have like beastie boys, the who, etc. so since the music stores are different for each country, i went over to the uk one and they had the essential oasis listed first! (lol, follwed by robbie williams).
so its got all of the stuff you'd expect (wonderwall, champagne supernova, live forever).

its really dissapointing though that they dont have any of the be here now singles on the store, as i think they had some of the best b-sides ever: (i got) the fever, street fighting man, flashbax. some great songs there.
