I found my Pegboy CD, and after some trouble with the home computer, was able to rip "Strong Reaction" from the laptop at work.
I've managed to find copies of "She's Got A Way," "Mad About You," "Solsbury Hill," and "Goodnight Saigon" on MP3, although Solsbury is not the Wellesley Widows A Capella version, and Saigon, unlike the rest of the disc at a 192 bitrate, runs at 128 bits.
I found the song from the Garden State
trailer, Frou Frou's "Let Go." Like I said before, since this recompile looks like it's going to span two discs, I think I'll compile a whole new 90-minute "mixdisc" including that song...
Of all of these, I think I'm most excited about the last one.
