Of course, the music is different and I don't like Oasis either (and especially Liam G., saw an interview two days ago, this guy seems pain silly).
But look, you say that "Liam knows that this record has to do as well as FOTL or people will claim it's a flop, no matter how good it is", but Liam often enough mentioned that he writes music for himself, not for the fans and he tries to avoid the mainstream.
No, I picked PWEI just as an example for friends who are musicians and then feature you later on on a record.
Plus, it's mostly the rec company caring about sales, I'm sure XL will do a nice advertising, (-hopefully not with stuff like sales forces or radiopluggers like all the pop-records are treated with-) so Prodge have to keep it low with the chart-ability.
The huge 'feat. Liam G. from Oasis' won't be on the cover I assume. But you were kidding on this anyway, were you?
