Are the bolds distracting or do they work out okay? I’m not 100% sure whether or not to keep them.

No, no, they’re great as they are!
Well done!
Very well constructed, nicely handled, and a straightforward plotline that is understandable.
Great job!

They make the title’s of the song clearer.
I like the last stanza. A lot.

However you can still be someone without that other someone.

Just saying.

Wonderful prose that presents a clear picture of emotions. Lovely!

I think this is my favourite entry so far, it reads perfectly, no jolts where you’ve had to work around a tricky title…

I try not to think of them as song titles, just read it as is, so I guess the bold made that a little difficult, but I can still tell that it doesn’t rely on the challenge element – good work. MH :)
