Mick Jagger says he's still hopeful about the possibility of another Rolling Stones album.

The veteran rocker, whose band's last full-length album was 2005's A Bigger Bang.

"I've got a lot of new songs, and songs I've written over the last couple of years," Jagger said.

"I've done really good demos for all of them, which I would love to record."

He added that, while he'd prefer to make a Rolling Stones album first, he would not be opposed to making a solo album if that didn't happen.

"I've got songs that would be great for the Stones, and I've got songs that wouldn't be perfect for the Stones," Jagger said.

The Rolling Stones will be on a 15-date North American tour this summer.

Jagger has also hinted that several autumn dates may be slated in addition to the summer tour dates, but has not confirmed any of these.
