Overnight ratings breakdown via Marc Berman of Mediaweek:

Thursday’s ratings by the numbers from New Orleans auditions:

22.63 million viewers on Thursday compared to 26.23 million viewers on Wednesday.

7.7 rating/21 share on Thursday compared to 9.7 rating/26 share on Wednesday.

Expected dip from Wednesday to Thursday but all-in-all not bad having nearly 23 million folks watching Randy Jackson take his shirt off.
