Hows to find products/music/anything from movies/tv series ?

I know this is OT, but since ten-forward was taken off-line there is no appropriate forum, so ......

I am often watching a movie or TV series and think "I wouldn't mind getting a pair of sunglasses like those", or "This music is great. What's it called ?". Now, I know that for movies they have a list of music on the credits at the end, but I'm wondering if there is an easier way to find out the information I'm after (eg. products/music used, and when they are used during the show/movie) ?

Are there any websites which offer what I'm after ?

BTW, does anyone know the make and model of sunglasses that:

a) Al Pacino wears in Carlito's Way ?
b) Prison Break: The agent who tortures and then tries to drown Sarah Tancretty (but then switches sides after being shafted by the President, and saves her from prison by corroborating her story) ?

 

For music in movies/commercials/shows you can check AdTunes.com Forums. And as with any forum, do a search first

As for Kellerman's glasses (prison break) check this thread.
