Fixing titles in bulk

used a YT converter, went through editing titles in windows media player but when i put them on my mp3 it shows (artistname-"title of song"-official/lyric video) is there a way i can change them in bulk so its just the title of the song and not have to do it 1 by 1? ive tried doing the tag-filename and the titles are all the same as they were before
thanks guy/gals

Could you show a real example?
If your problem needs regular expressions to solve then every character counts.

i did the top 3 but i want them all to be like the top 3 without having to do them singularly.
i went into the tag-filename and set it to " %title% " but they stayed the same unless i do them manually

You have to define which part of the filename represents which field.
For

try Convert>Filename-Tag
Format string: %artist%-%title%

Could you adapt the screenshot in such a way that it shows a complete filename for the files starting with "Three days grace"

basically i want to get rid of the highlighted sections cuz most of the 200+ tracks are formatted like this.
i tried your suggestion and it just added the artist name twice for the ones that already had it and once for the ones i fixed manually.
im computer illiterate so thanks for helping me cuz i already spent 2+ hours fixing the titles in media player

If you define a pattern then the treated files have to match that pattern (computers cannot really read) - otherwise you get surprising and mostly unwanted results.

For the files with the highlighted pattern try:
Convert>Filename-Tag
Format string: %artist% - %title% (%dummy%
for files without parenthesis try:
Format string: %artist% - %title%

You see in the preview what the likely result will be.
