Does that mean between the 15 track CD and the bonus downloads that we're ultimately getting every song that didn't make U22?
22 + 15 + 2 = 39
There were 48 tracks in the running for U22. At present, that means 9 songs remain that haven't been accounted for on U22 or FTGU, and we know more bonus downloadable tracks are coming.
There were 46 tracks total. There have been three bonus downloads. Unknown Caller was bonus to U22. And now we have No Line and Spanish Eyes.
22 + 1 + 15 + 2 = 40. So currently, there are 6 left over tracks that might not see light of day. U2.com says more downloads are coming, but they don't say whether they'll be more bonus tracks, or if they'll be tracks included on the CD.
It looks like New Year's Day, Boots, and Electrical Storm will be on the CD based on the music player embedded in the news article. So the following tracks are the ones left that could be used.
