Normal or conventional ideas (10)

I believe the answer is:

(Other definitions for mainstream that I've seen before include "Conventional, normal" , "Relating to what is normal or standard" , "conventional activities" , "Current" , "In accordance with what is normal or standard" .)

I've seen this clue in The Times.
