The challenge from a friend was a regular cd-length album with no words or voices - not just no lyrics. Which left out Cocteau Twins and Laurie Anderson, among others. The unstated part was that she's using this to annoy the officemate who says that any voices distract her, but not annoy my friend. My intent then is to mix and match genres - the all jazz or all classical mix would have been easy, but what's the point of that?

Anyway, the mix:

Pepperland - The Beatles
Jessica - They Might Be Giants (the Allman Brothers cover from the "Why Does the Sun Shine" EP)
Marsh Rose and Green Briar - Annwn
Childgrove - The Waits of Southmarch (English Country Dance tune)
Cantiga Medley - Broccelnade (however they spell it)
Trademark - Eric Johnson
Meniscus - This Mortal Coil
September Fifteenth - Pat Metheney and Lyle Mays
Der Paranoide Engel - "Wings of Desire" soundtrack
Five Per Cent for Nothing - Yes
Blue Monk - Theloneous Monk
Skating - George Winston (the Vince Guaraldi tune, from A Charlie Brown Christmas)
The Wonderful Sea Voyage (of Holy St. Brendan) - Alison Brown Quartet
Mood for a Day - Yes (my only group duplication, but way different styles)
Horizons - Genesis
Final Motif - Birdsongs of the Mesozoic
Think Music - from the collection "Mozart TV", the Jeopardy "theme" in the style of Handel variations. On harpsichord.
Orange Blossom Special - Glenda Faye
Honky Tonk Train Blues - Emerson, Lake and Palmer
Bride of Rain Dog - Tom Waits
Linus and Lucy - Game Theory (for fuzzy electric guitar)
The Internationale - Ani DiFranco (not with Utah Philips, but on the album with him)

I had to pull a couple of tunes off the original mix because they either had little bits of sound at the end I hadn't realized (and I'm just doing quick and dirty burns) or they just didn't really seem to fit. "Two Rivers" by Jeff Beck and "Devil Drums" by Lee Press-On and the Nails are great, but, alas.
