I think "Its victims left in *predicament*" doesn't go with the rhythm of your poem. "Fright" might work better.

Some other suggestions to improve the rhythm:

> For there is no other *quite* like it.

Also, some repetition here might help:
>For from the outside all looks well,

>But *from the* inside they are trapped, 

Otherwise, good job.


So... some basic issues that I see with the piece: there's a AAA rhyme scheme set up at the start, but it's inconsistent throughout, and some lines have the same end-rhyme (dance/it).  Not sure what 'Ney' is or why it's capitalized, but I think you mean 'Nay' as the archaic form of 'No'.  

Some of the pronoun use needs work, especially in lines like 'But these ones you cannot see them,' (plural pronouns referencing the singular 'bug') and 'While companions think they're smiling,' (they're is unclear in reference to the companions or victims, grammatically).

There's switching back and forth between first and third person viewpoints as well, which makes following the logic of the piece somewhat harder.  

I think the piece could be revised/tightened to roughly half the current length and the metaphor/base idea obscured better, as it's explicitly stated in the penultimate line.  

I would like to take the chance,

To talk about a dance,

I should rather say the dance,

For there is no other like it.

You see there's not a chance to fight it.

Its victims left in predicament,

For from the outside all looks well,

But inside they are trapped, 

While companions think they're smiling,

But Ney that is the bug,

That comes along and bites you,

But these ones you cannot see them,

They come disguised as music, 

Make you twitch and writhe in rhythm,

And now you've heard our jingle,

I'm feeling somewhat smitten.
