Here are some nudges
You are looking for words that match a particular pattern
What kind of pattern you say? For what's it's not, see the clue for 69A
So you know what the pattern isn't - for further clarification, see the clue for 7D
If you've found 7 words that fit the pattern, you're half way there (and, perhaps, Livin' on a Prayer)
Speaking of songs, see the clue for 58A
It may help to use a highlighter to note all the words that match the pattern you're looking for (or use screen capture and markup tools for those solving on a device)
