How to locate "Top Gear Music" from "Extreme Music" website? They don't want to tell you anything.

Often times I hear a really nice track on the Dave screenings of the original Top Gear (not the new "reboot") but ID'ing and finding these tracks is virtually impossible. I found 1 in the past and only because a lot of others were asking for it and finally someone got an answer. A lot (all?) of these tracks "apparently" come from a site called "ExtremeMusic.com" but if you look on that site, its pretty much impossible to find anything in particular, even though they have 100's of tracks. You type "Top Gear" or "Dave" into the search bar and you get zero results, yet apparently most of their music comes from that site. I even opened a live chat with them but I've spoken to brick walls that are more forthcoming than their helpdesk lackeys, they won't reveal ANYTHING unless you're a professional client lol. I basically got given the "corporate cold shoulder".

I'm out of options and ATM I don't have an operable smartphone so I can't use Shazam. Can anyone help me out here? How do you find what you WANT on Extreme Music? Or just, how do you find the music Dave uses in Top Gear??? Thanks.
