Why does BBC America change all of the music on Top Gear from the original to some cheesey bad stuff that doesn't work as well and makes the show more boring?

The BBC doesn't spend the money to get the rights to the music everywhere. BBC openly dislikes America, because we don't HAVE to pay the BBC, whereas in England if you want TV at all you have to pay the BBC. Because they have less of a market, because they would have to work harder for the same pay, and because rights for music are bloody expensive, they'll pay for the rights to music only in region-locked DVDs and on british television. BBC America usually has one or two kids on staff who can slap together music for them, mixed with music the BBC and BBC America have purchased unlimited rights to use and royalty free music.
Obviously I would never do this because that would be wrong, but apparently if you google top gear, and put in the season and episode, and look for the episodes that have been uploaded to streetfire.net, you can watch the episodes with the original british music.
