"Glad" zooms into the Hot 100's top tier spurred by a 19-3 charge on Hot Digital Songs (188,000 downloads sold, according to Nielsen SoundScan). While the song was already building at an impressive pace, having gained in each of its previous five weeks on Hot Digital Songs, its exposure on "Glee" aided the original version's fortunes. The "Glee" cover concurrently debuts on the Hot 100 at No. 90 with 37,000 downloads sold. The show's Grant Gustin (along with fellow members of the fictitious show choir troupe the Warblers) performed "Glad" on last week's mid-season finale.
So it seems with the exception of "Stand", all songs of this episode made it into the top 100 of the Billboard charts.
