Sometimes it would be helpful if there were more details on differentiating between versions of a particular track...other than that, really...the information contained on this site is amazing. Also...and this may be something you're already considering or working on...it would be nice to include a section on or listings of "semi-official' tracks. I'm thinking of things like the Daniel Lanois version of "Thank You" that was available as part of a podcast downloadable from I-Tunes, the Alex Metric remix of "...Crazy Tonight", which was officially sanctioned by the band and played by him during a radio set, but never released, or the song "Don't Come Knocking" which never had a true commercial release but was in the movie of the same name. Thanks for listening, and, if no one else says it, truly, thanks for this site. i can't explain to you what a helpful resource it's been over the years. This and one other U2 site are the only ones i make sure to check every single day.
