Hi, Eric, and welcome.
I know exactly what you're saying. Topdown's point is that as a search engine, Chordie goes and grabs what is out "there", whether it be right or totally wrong.
One thing to do is when there are multiple versions of songs, look at the Accuracy rating for the song and go for the higher-rated ones first. While highly rated songs aren't necessarily 100% accurate, they're usually close. With a few tweaks here and there you can get them sounding right.
Another thing to do is scroll down to the bottom and look and see if there are any comments entered for the song. That is one place where chordie users can suggest changes/improvements to a version of the song that the search engine finds. Here is an example of one that I commented on a while back:
