One my most favorite Adele songs. My first, to be honest. Amazon suggested another song, and the preview intrigued me enough to check out all of 19's previews. Because Hometown Glory had two previews (from two different albums) from two different points in the song, I got an idea how the song progressed and decided to buy it.
It's simply beautiful. It's simple, the lyrics give you a sense of nostalgia, and Adele's voice is strong and powerful. It's the reason why I eventually just bought the whole cd.
If you've never heard anything from Adele, I strongly suggest to start with Hometown Glory. If you like it, I suggest Daydreamer, Melt My Heart to Stone, and My Same (or just go get the whole damn album : )).
