As JoJo continues to battle her label to release her third studio album, the talented singer celebrated her 22nd birthday by giving her fans a taste of what they can expect from the forthcoming studio set with her new mixtape, 'Agape'.

The set, which clocks in at under thirty minutes, features contributions from Austin Brown, Elijah Blake, Scott Bruzenak, Kelly Parker and Boi-1da. Read the singer's letter to her fans and download your free copy of the mixtape beneath:

My name is Joanna Noëlle Levesque and I’ve loved music more and longer than I’ve ever consistently loved anything in life. Music wakes me up and puts me to bed every single day, without fail. I obsess over it. I want to know everything about it! I want to snuggle with it at night. I want to be as close to it as friggin’ possible. When I was 17, I wanted to make it official. I snuck away from the hotel room my mom and I were staying at and got a tattoo. On my ring finger on the left hand; a treble clef. BAM. To remind me not to let anything, or anyone take precendent over the perfect mate I had in music. I feel often like I’m better explaining myself through song. Better than trying to talk about it. The older I got and the more music I inhaled and was exposed to, songwriting and interpreting other people’s songs became my most gratifying form of release. I felt the passion of my favorite artists coming through their records and I always wanted to emote like that. To be so powerful and connected so as to radiate such energy and truth.

I thought about naming this collection of songs “Live Free or Die” after the New Hampshire state motto (which inspired the tattoo on the back of my neck), but upon further thought, it sounded dramatic and militant and scary. And that it SO not what this is all about! Its really about friends coming together and bonding over a mutual love for music then seeing what grows out of it. Not about industry politics, agendas, empty-promises, ego, swag, pretension, or a budget of any kind.

THANK YOU for listening. You don’t know what it means to me to have a platform to express myself and interact with you. Doing what I love is an honor and a privilege. One that I take to heart. Oh to be making music in the modern time…The internet has changed my life, man! Who’da thunk it. I’m thankful and more excited than ever for the future. My story is unique, confusing, and tumultuous at times. But I wouldn’t trade it for the world.

In spite of the continued delays that plague her 'Jumping Trains' album, singer JoJo keeps it moving and releases another offering from the recording sessions of the set in the form of "Demonstrate", which was produced by Noah Shebib.

Brilliant, magical  and mind-blowing are just a few of the words that can describe the track's three and a half minutes of music heaven. Talent of JoJo's magnitude deserves to be heard and if this doesn't finally secure her album a release date, then I'm worried that nothing ever will. Listen to the vocally-astonishing cut below:

With her album 'Jumping Trains' slated to arrive in stores later this year, singer JoJo has premiered "Sexy to Me" - a buzz single from the forthcoming project.

The confident track was produced by Danja and recalls the work he contributed to Britney Spears' fifth album 'Blackout', and just like that entire album, 'Sexy' lives up to its name and provides an added dose of sass. Simply put, it is HOT!!!

Pop songstress JoJo has released the video for "Disaster", the lead single off her upcoming third album 'Jumping Trains' (due in 2012). Watch the clip below:

After a five year absence, pop songstress JoJo returns to the music scene with "Disaster", the first single from her forthcoming third album 'Jumping Trains'.

Describe by the vocalist as a "distant [and] edgier cousin" of her 2006 hit "Too Little, Too Late", the Mario Marchetti-produced single, which talks about a messy break-up, thrives on her ascending vocals and the engaging production.
