Python findall - ignoring some results

I'm doing a program that in the future will interpret the search results of videos from YouTube. My snippet version of code is aimed to extract pseudonyms of artists from the song title.

Example

I have a title saved in string: "Drake ft. DJ Khalid, Nicki Minaj - 'Why Futures' (Official video)" and I would like to ignore the word 'Futures' for findall function (because it is part of title song, it is not rapper's/artist's nick), which is between the ' and " characters. Additionally I have a problem with 'DJ Khalid' because findall returns two nicks of rappers (DJ Khalid and Khalid) instead one nick (should be same DJ Khalid).

Code

edit_string = "Drake ft. DJ Khalid, Nicki Minaj - "Why Futures" (Official video)"
rapper_name = open_csv() #list of rapper's nicks

new_title = []
for rapper_name in rappers_list:
  yer = ''.join(rapper_name)
  if re.findall(yer.lower(),edit_string.lower()): new_title.append(yer)
new_title = ' x '.join(new_title)
print(new_title)
edit_string = new_title

Results

Actual result is: Drake x Khalid x Nicki Minaj x DJ Khalid x Future (because in my list of rappers unfortunately I have someone who is called Future)

Shall be: Drake x DJ Khalid x Nicki Minaj

How to do it in the best possible way (best optimisation)? Thank you in advance for all your help.

Credit to @FailSafe for pattern. OP, this answer demonstrates what @FailSafe suggested is indeed correct: 

import re

edit_string = "Drake ft. DJ Khalid, Nicki Minaj - "Why Futures " (Official video)"
rappers_list = ['Drake', 'DJ Khalid', 'Nicki Minaj', 'Future']#open_csv() #list of rapper's nicks

new_title = []
for rapper_name in rappers_list:
    yer = '(?i)\\b'+str(rapper_name)+'\\b'
    if re.findall(yer.lower(), edit_string.lower()): 
        new_title.append(rapper_name)
new_title = ' x '.join(new_title)
print(new_title)
edit_string = new_title  

Output: 
## Drake x DJ Khalid x Nicki Minaj
