There are many who say that this album is 'too short' and that it should include songs like Stay Young, All Around The World etc. Personally I disagree - I say that this is an ace best of and the envy of most other bands out there.
The songs on there meld near seamlessly, which is a hard thing to do as I know from compilation writing. In fact its eerie how well The Importance Of Being Idle blends so well with Wonderwall - you could almost think it was from the same album! The songs themselves are also the real classics, without including all the tunes that have unpleasant memories associated with them (e.g. D'you Know What I Mean? being the harbinger of their 1997 downfall, even though in itself it is a good tune).
In fact, to add to this point, it is neat how Oasis have airbrushed their history. It is notable that the first sycophant in the booklet excludes the whole of Be Here Now and instead goes on to Oasis' latest stuff. Although this is high pretentiousness, it does make sense in a way to ignore the bad bits, or the reminders of the bad bits (e.g. Gas Panic! and even Little By Little).
As a best of, the album does the job in that it shows a tempting morsel of the best and sacrifices the ones that may taint the picture even if they were Great. I would also add that my favourite album is Standing on the Shoulders (which is barely included) but I think its depth would be poorly spent on what should be an otherwise radiant collection.
