Brit award-winner Adele has admitted she is currently struggling to write songs for her second album.
The Tottenham singer, who hit the number one spot with her single Chasing Pavements and debut album 19, explained touring is affecting her ability to complete new tracks.
"Even though I'm given time to be on my own, the last thing I want to do is write a song," she told BBC 6 Music ahead of performance at the Little Noise sessions in Islington, north London.
"I've written about six songs. Four are really bad, just because I'm kind of getting back into it. Two are alright."
She added: "I just want to make sure I write a good record. The better your record, the more opportunities you get."
Having collaborated with The Raconteurs on their single Many Shades of Black and performed onstage with Burt Bacharach at the Electric Proms, Adele has her sights set on working with the likes of Justin Timberlake or Beyonce.
"But it's a bit inevitable and generic... doing one with a big star is expected," she went on. "So I'd quite like to do one with an up-and-coming person.
"I'd also love to work with Alison Krauss. I love her so much, but I think that kind of record will come when I'm on my fourth or fifth.
"I'm still a bit of a pop tart and that's what I want to remain for a while."
The Mercury nominee said she hopes to have completed her second album by autumn 2009.
