Fail & Pause Features

after playing guitar hero for awhile i was thinking

why doesnt tapulous have a "fail" feature on songs.
it doesnt gotta be big just a small circle gauge with a needle that moves on how well your doing.

and after playing rock band (ipod version)
when you pause the song then resume, the song doesnt start right away
the note board flows for a bit then the notes come
that would be nice in ttr games
(especially extreme tracks)

i also had a question on when we'll be able to import our metallica tracks into ttr3?
(if we can)
