From what I've learned, that album had a bunch of producers involved, all with what they thought was the best sound. It was a rather frustrating process for the band to go through as they had so many differences to how they wanted the final product to be. If you listen to the entire DSABH album, you'll hear different production techniques through out the songs (heartache every moment, dont close your heart, please don't let it go all sound polished up compared to lose you tonight, in love and lonely, love you like I do all sound more raw) So all the alternative tracks will sound much differently than what has ever been released. Salt in our wounds has I think 3 different versions stemming from different releases, same with lose you tonight. Personally, I'd love to hear alternative versions of the entire DSABH album.
