LP have another #1 album on billboard.com, but their album sales won't have Warner celebrating as 241,000 units sold pales in comparison to the 623,000 that MTM sold in its 1st week. Obviously, the band still has many fans, but they have definitly lost a significant amount. I think we should also acknowledge that a portion of the 241,000 people who bought ATS don't like the album.
I think that LP needs to either improve their new sound so it can hold its own or start producing albums that cater to their entire fanbase. I think ATS is a What Ive Done or two short of being a great album and if the band wants to leave their past behind they got to write better ballads. Their best ballad/mid-tempo songs (Iridecent and Waiting for the end) fall short of being great imo and aren't good enough to make many fans forget about their older stuff. The band set the bar high with HT and will need to write better songs before they can move on from that. I think that most people would agree that neither Iridecent or Waiting for the End are in the same class as the best ballads that come from U2 or Cold Play. So until that bridge is gapped, they should cater to their entire fanbase.
The faster songs, which are probably aimed at their older fans, leave don't quite deliver and I fail to see what's wrong with including 2 or 3 songs that sound like stuff from HT or Meteora in addition to their new stuff. You can have it both ways and keep everybody happy while experimenting at the same time. I don't see the point of intentionally making many fans unhappy. Who cares what the critics think.
