"Reason" is a song by German girl band No Angels. It was written by Thorsten Brötzmann and Alexander Geringas and produced by the former for their debut studio album Elle'ments (2001). "Reason" is a piano-led pop ballad with soft string arrangements and lyrics that talk about reminiscing past memories with a loved one. One of the slower songs on the album, its original version, entitled "That's the Reason", served as the closing track on both the original version of Elle'ments as well as its Special Winter deluxe edition.

"Feelgood Lies" is a song by all-female German pop band No Angels. It was written by Pelle Ankarberg, Charlie Dore, Niclas Molinder, Maryann Morgan and Joacim Persson for the group's third studio album Pure (2003), while production was helmed by Molinder and Persson under their production moniker Twin, with Ankarberg serving as co-producer. A dark urban dance pop song that is built upon a heavy guitar riff and uplifting strings, the subjects of "Feelgood Lies" are revenge and karma. Not wanting to feel broken-hearted, the female protagonist warns a love interest to check his alibis.
