search for artist from iTunes
So, say you got this one great track in iTunes, and you want to look for more music from the same artist. Here’s a simple little script that can ease things up a bit.
This script makes a Amazon search in Firefox for the artist, but as you’re guessing you can make it go to what-ever site you like and search for content. Open the script and replace the url with a new url and save. You can also make it use Safari instead of Firefox.

(This script was pretty nifty in 2010! But no longer available as of now)
To install it, place it in your home folder/Library/iTunes/Scripts
If that folder doesn’t exist – make a new one and call it Scripts.
Quit iTunes, restart and an applescript icon should appear in the iTunes menu bar, with your script ready to be clicked on.
