Appending two lists

[jingham06]

Say I have a list:

songs([15steps, jigsaw, bodysnatchers]).

but this is within another list.

frame(radiohead, [songs([15steps, jigsaw, bodysnatchers])]).

How would I go about adding a new song to the list, so far the closest i've managed to change it to the follwing using append:

frame(radiohead, [songs([newsong]), songs([15steps, jigsaw, bodysnatchers])]).

But I want them to be in the same list

Thanks for your help
