Edited sentence: Coldplay had already tasted critical and commercial sucess, but the opening of X&Y bettered anything they had previously aspired to.The album opened at #1 in the UK, but that wasn't so much surprising as the incredible sales, which totalled up to 464,471 copies of the LP in its first week, making it the second most sucessful opening of any LP ever in UK history (after  Oasis' Be Here Now first week sales of 695,761 in 1997, which is a record unlikely to be broken for a long time)
