If you like your rock mixed with a bit of pop, and you're into Miley Cyrus and Hilary Duff, then you will absolutely love this.
The song's called Free and it's one of those tracks that really gets into your head after a couple of plays.
The track features strong vocals from Dani, a powerful chorus accompanied with guitars and of course, a heavy drumbeat. The track sounds pretty American to me, which isn't very original, but it's a popular sound with lots of pop fans.
You might already be familiar with Dani's debut single, it was also the theme tune for the CBBC sit-com Dani's House, which she also starred in.
Dani really belts out the chorus in this track. With the words: "Sometimes I feel like breaking free, let's lift these chains." Is she trying to tell us something?
Maybe she wants to escape the acting world and break into the music scene.
And with these lyrics: "Lets rock this wave right out to sea, I'm craving for sunlight, the wind in my hair," it sounds like Dani just wants to enjoy herself in her new found music spotlight.
Will you still be humming it next week?
The video is bright, fun and goes really well with this track. I've got to say the chorus is the catchiest part.
Each verse washed over me, but the chorus really stuck in my head. I've been humming it without realising - that's always a good sign.
Will it make the charts?
This is tough one for Dani. It's always hard for soap stars to go from an acting career into a music career, so it might be quite tough for her.
A lot of people will recognise Dani from Tracy Beaker and Dani's House which could be a good thing. It means she already has thousands of fans who will love her pop/rock sound.
Then again, this single is quite similar to other American pop stars like Miley Cyrus - maybe a bit too similar.
Will it make the top 10? I reckon she's got a pretty good chance. Good luck Dani!
