I have no idea what the reviewer who gave this 1 star is on about, it is what it is - a double album, 1 disc with a selection of Chicago's best songs and biggest hits,and likewise for Foreigner on the other disc. Both fall under the genre of late 70s/early-mid 80s American Soft Rock, so most people who purchase this are likely to enjoy the offerings from both bands (unless there is some Blur/Oasis type rivalry between the two that I'm not aware of...) This double album features all the songs that most people, who are vaguely familiar with either band would expect to hear, plus you get to hear quite a bit more of what both bands are about. For example you will get to hear Chicago without Peter Cetera on lead vocals during the later part of the Chicago CD - if you didn't know better you would think you were listening to another band, as their sound changes completely. Instead of Rock Ballads, their music almost has more of a 'swing' feel about it. Unfortunately no "Glory Of Love" though, probably because it was a solo effort from Peter Cetera, rather than a Chicago release. Foreigner's CD is superb and a real joy to listen too. This double album is for those who know and like a few songs from each band, like myself. Real fans of these groups would probably go for individual albums, or 'Best Of' albums with a more a in depth collection of songs, such as "No End in Sight: the Very Best of Foreigner" or "The Best of Chicago: 40th Anniversary Edition" respectively.
