The Rdio app and the iPod App

I know it’s nerdy, but I’ve been comparing the Rdio iPhone app with the iPod iPhone app.

If I were making a music app for the iPhone I’d try to do something similar to what Rdio has done: make the app look and feel as much like the Apple app as possible.

But the Rdio iPhone app doesn’t look exactly like the iPod app. The arrow icons are different, the song list icons are different, and the spacing on the play and track navigations are a little different.

I wonder why.
