You can soon expect to pick up a free song of your choice from iTunes with every concert ticket you buy at Ticketmaster. No gimmicks, no catches. Buy a concert ticket, get any track you want, gratis.

The other side of the promotion extends a program where last year, for example, pre-orders of Stadium Arcadium from iTunes got RHCP fans early access to tickets. By pre-ordering “select digital albums,” you’ll get a crack at that artist’s tickets before the rest of the non-iTunes-using barbarians do. No word yet on which artists are participating, though…

Finally, later on this year, rather than buy separate gift cards from each, you’ll be able to drop dime at Target on a single “Ticketmaster + iTunes gift card pack” that you can use at both Ticketmaster.com and iTunes.

All in all, it sounds like a great deal for iTunes and Ticketmaster customers, since there seem to be no strings attached. This is especially good if you want to preview the opening band you’ve never heard of before your subjected to 45 minutes of their music.
