A very nice song, however, I highly object to your notion that this sort of music is somehow the only real, meaningful kind of music, compared to "shallow, bad pop." If all music was like that song, the world would be a pretty dull place.
Pop music is lively, innovative and constantly developing. To say that it's "soulless" just because it is often stylish, fun, electronically produced and doesn't present itself in a pretentious "deep n' meaningful" way is ridiculous. Girls Alouds' songs and some other chart music is actually written by an innovative production team called Xenomania who are experimental with pop music by, for example, changing traditional verse and chorus structures (see 'Biology'.) In fact, a great deal of pop music has hidden depths, as it is often built on minor chords, so although it often sounds upbeat and happy, it also has a sadder side. I am not that I'm saying all pop or chart music is good, though, obviously.
Perhaps what you are saying is that there is not much peaceful, acoustic music like this around, which I'd be inclined to agree with and perhaps it would be nice if there was a little more of this that charted. It doesn't mean that everything in the charts is bad, though, even if it's not to your taste. If you can't objectively see that pop music has value, innovation and is far from being "soulless," then it is you who is shallow and not the music.
