With most albums, there are a few songs I like, and the rest are just okay. With these albums, every track is absolutely worth listening to and appreciating, all the time. Now, your mileage may vary, obviously, depending on your taste in music, but for what it's worth, I do have a pretty varied choice in likes. In no particular order:
Imogen Heap - Speak For Yourself
I've listened to this album at three varying points of my existence, and every time I've sat down and listened to the album, every track resonates with something. There is a full spectrum of emotion and expression within the content of the album, and Immi's just a talented artist, as a whole. This is probably the only album I've ever called a masterpiece.
The Bravery - The Bravery
