This one doesn't appear to be the case. Certainly not when browsing a list of songs in the library. I have just compared and it can fit an entire long title where the iPod list cuts it off "Anti Warhole on the Dancefloor" compared to "Anti Warhole on the Dancefl..."

Even the album/artist text under the song title shows more characters in Amp.

I'm pretty sure your list is otherwise going to be as long as mine and with many of the same criticisms for Amp.
