I'm in agreement icarius. The new tune is indeed soothing and relaxing. It certainly beats what they replaced

Keep an eye out on the Jetstar.com | Downloads page, as they may post the tune and/or ads there (the old TV adverts were availlable for d/load here, but have since been removed).

If not, search for "Jetstar" on websites such as YouTube. They usually have a good range of videos relating to almost everything (got QF 744 rotations, QF ads etc).

It's not childish one bit - I'm interested in Qantas/TV News/Program themes myself (cough, cough Mediaspy.org)

Hope that helps..

Cheers ^
