All Access Music Group posted a (radio?) edit version of “Tomorrow” on its website. The edit version, which is 3:43-long, has a shorten musical intro. The remaining part of the song is unchanged. The length of the album version, or at least the version posted on Rollingstone.com, is 3:56.
You can listen to the edit version at allmusic.com, on the Triple-A Future releases page under “November 21”. (link no longer available)
Thanks to Rick from the cranberries.me community for the info!
