T-ara is making a comeback with not just one, but two title tracks!

Instead of just "Number 9", the girls will also be promoting the medium tempo song "I Know the Feeling", which is a bit slower and emotional with its heartfelt lyrics. Member Eunjung apparently helped arrange "I Know the Feeling", making it a song that fans are especially looking forward to.

So check out the girls' transformation and their new sounds through the MV above and below for "Number 9" and "I Know the Feeling" as well as the other tracks from their mini album 'Again' in the playlist below!
