The rarest track, and I'll be surprised if anyone has heard it, is Soul Tattoo's "Stutter." I heard it one night from a local college radio, and as the norm, I just had to get the CD. Another possible rare track is Paw's "Couldn't Know." And the other (possible) rare track would be Inclined's "How Deep Is This Well?" Inclined had that Spin Doctors feel/sound going for them. Urge Overkill's "(Today Is) Blackie's Birthday" off '91's The Supersonic Storybook, their (imo) best album.
Spacehog's "Cruel to Be Kind" was the reason why I needed the CD. And, how come you rarely/never hear Dionne Farris' "I Know" - the track is still solid. Anyway, the whole mix is solid. Enjoy!
