New Music For PR2?

[Different]

let's say that happens... well my music is being released under the Creative Commons license. This means I am not making any profit with the track. Additionally, this means it has to be used, shared, modified, or even tweaked alike by any other producer or users under the same license, therefore, making whatever 'song' or track that might sound even a few decibels like any commercial or even non-commercial track, be a remix (depending on the case) or ''work inspired by (blank)''

So me being sued over that is waaay off any possibilities. Them trying to ''take down'' a track that was released under the Creative Commons license without any lucrative ends... is a sue that will just go nowhere, legally speaking. 
Basically trying to take down something that is free of copyright and literally not affecting them (the music record company) in any way, shape, or form is just not something a huge music record company will go out of their way to do.

And let's be real... a huge music record going after a small YouTube video one-off hit made by a random,  underground independent music producer, not affiliated with any major discography company will be 100% a PR disaster. That'll be a horrible look for them. Which is not the goal for most companies.

Now, let's say that you worked really hard on this one song that you know will be a huge hit. So, now you have strong intentions on making a profit off of it on iTunes, Spotify, YouTube, Deezer, etc. So, now you're thinking it's a great idea to go and start off with YouTube first, getting a Creative Commons license (with lucrative benefits) and a Mechanical license under the same deal. But, of course you've already gotten it copyrighted, first.

Unfortunately, your subconscious mind has successfully manipulated you into thinking that you've never done or heard this song before, until you learn the hard way from a major record company (that you've never heard of before) telling you that you're under hot water with them because your melodies sound 100% identical to one of their hit songs. Now you're being sued for $1 million. But, of course they don't come after you until your hit song reaches 10 million views on YouTube (making you over $90k in lucrative profits), and your song on Spotify gets millions of streams as well.

How would you personally deal with this huge lawsuit, now? Do you get a lawyer or what? I ask this because I plan on copyrighting and making a profit off my songs, but they sound very similar to hits.
