Society always celebrates the records that top the Billboard 200 album chart. Back of The Billboards is a Music Times weekly segment that looks at the opposite end: the new record that finished closest to the back of the Billboard 200 for the previous week. We hope to give a fighting chance to the bands you haven't heard of. This week we look at Number 1's, a collection of hits from Marvin Gaye that *****ed the Billboard 200 for this first time last week, and whether a certain lawsuit involving a certain Robin Thicke and Pharrell Williams single had something to do with it.
