Week Ending Oct. 16, 2011. Albums: After Teen Stardom

Joe Jonas' solo debut album,Fastlife, enters The Billboard 200 at #15, with sales of just 18K copies. That's a far cry from Jonas Brothers' fastest-selling album, A Little Bit Longer, which blew through 525,000 copies in its first week in June 2008. Simple math tells us that for every 29 fans who bought that album, just one die-hard loyalist sprung for this album.

The tally for Fastlife is about one-quarter of that rung up by Nick Jonas & the Administration's Who I Am, which debuted at #3 in February 2010 with sales of 82K. (The third member of the trio,Kevin Jonas, has yet to release his first post-JoBros album.)
