On 28 July 2003,
Roadrunner Records serviced "Someday" to American
modern rock radio as the
lead single from
The Long Road. The following week, it became the most-added song on three radio formats: modern rock,
active rock, and
mainstream rock, with a total of 188 adds. Within two weeks of its release, it had gained 3,000 plays, and within four weeks, it was a top-10 success on all three formats plus
heritage rock, becoming one of the few non-
hip-hop songs of 2003 to experience instant success on radio. Following the song's boom on rock formats, Roadrunner then targeted pop formats, shipping the track to
hot adult contemporary,
triple-A, and
contemporary hit radio (CHR) on 8 September 2003. It experienced similar success on CHR, entering the top 10 on two
Billboard pop airplay charts and giving Nickelback their most enduring hit on both. The first physical format of "Someday", a
CD single, was issued in Japan on 29 August 2003. The CD contains both the single and album mixes of "Someday" plus the
B-side "Slow Motion", which was included only on the Japanese pressings of
The Long Road. A CD with the same track listing was released in Canada, with a longer version of the single mix. In Europe, the Japanese version of the CD was released as well as a two-track CD single that contains the single and album mixes. ==Critical reception and legacy==
