I quite like the Shins for the record. I'm not sure this guy really counts as an integral part of the band though. Looks like he was a member for 5 out of a 22 year career and only on one studio album.
3 top 20 albums in the UK for the record though YoungWillz. Wincing the Night Away went Silver and was a #2 in the US. 4 top 100 singles in the UK. Not sure why you think they didn't chart.
EDIT: Ah, you were talking about this specific chap's record in the Shins. Well, he didn't even appear on their 2012 album, so his involvement in the Shins is probably a complete red herring. However, newspapers in the UK have clearly heard of the Shins and thus not bothered to find out whether he was an integral member or a peripheral one before firing up the obituary squad.
