I'm very inspired to keep with the theme. The prelude is the central musical theme. The soundtrack was noted for lack of a central theme. This season makes use of two pieces of theme music. There are considerable differences in the style of presentation of each theme. The city became part of the Seleucia theme. O'Donnell credits part of the success of the "Halo" theme to his background writing jingles. The poppy is a recurring design theme. Quick Styles are galleries with a range of styles based on the current theme. The first ending theme is by Vistlip. It is also suggestive of the overarching "travelling" theme of the album. This is a version by composer Dario Marianelli of Purcell's "Abdelazar" theme. Reaction to the new theme was mixed. This phrase became the "Warszawa" theme. Accordingly, Oldsmobile received a new logo based on the familiar "rocket" theme.
