Got my
Blu-Ray boxed set from Amazon today. Don't think I can watch 16.25 hrs of Season 1 + over 2 hrs of special features before tomorrow night, but I'll at least watch the features.

Special Features:
All four discs have Glee music jukeboxes. The fourth disc also has:
Glee Sing-Along Karaoke
Staying in Step With Glee
Sue's Corner
Bite Their Style: Dress Like Your Favorite Gleek
The Power of Madonna
Making of a Showstopper
Welcome to McKinley!
Glee Music Video
Full Length Audition Pieces
Fox Movie Channel Presents Casting Session
Deconstructing Glee with Ryan Murphy
Dance Boot Camp
Jane Lynch A to Glee
Meet Jane Lynch
5 Things you don’t know about Jayma
7 Things you don’t know about Cory
6 Things you don’t know about Amber
7 Things you don’t know about Chris
Video Diaries
It's unclear if the
7-DVD set has the same special features, but both say 1045 running minutes, so it probably does.
