Should a comma precede "meaning that"?
"I have a song, meaning that I'm now a composer." Should there be a comma before "meaning that"? What type of speech is "meaning that" and how do the rules apply?
Here's a site that puts a comma before "meaning that".
Solution 1:
Not an authoritative answer, but you're joining two separate/related ideas which benefit from the distinction, which is the purpose of a comma. So it's not specific to the phrase "meaning that":
I have a song, so now I'm a composer
feels better than
I have a song so now I'm a composer
