Posting a blog to twitter but adding a handle to it

Hey Guys,

So my website doubles as a music blog and the issue I’m having is trying to get someone’s twitter handle to show up in the description when my blog post is published to twitter. Right now my posts are automatically posted to twitter.

Basically say I write a post about Joe Smith’s new song “Words”
When it is posted to twitter I want it to say “Check out the new track ‘Words’ by @joesmith”

There’s gotta be a plugin that will allow me to do this. All the other music blogs are able to do it, but I’m having a hard time finding the right plugin on twitter. If anyone can help me I’d greatly appreciate it!

Thanks
