It should be noted that, in addition to the new songs produced for the 2nd season of Attack on Titan, this soundtrack release also includes songs from previous Attack on Titan soundtracks, most of which were only included with certain limited edition DVD/Blu-ray releases.
I've listed those songs below for easy checking.
