Are you referring to the Apple web client or this one in being much better?

Yeah I don't think it is any faster or more stable than the actual Apple web client. They probably use the same API's. Plus lots of considerations that applies to any website. Is it available in multiple languages? How accessible is it? Does it work on older browsers? Also, digging around, the Apple web client seems pretty up to date. Isn't old software. I like the search feature though on this.

Yeah looks like you can get Chinese pages as well. https://itunes.apple.com/cn/artist/taylor-swift/159260351
