Use the playlist function on your iPod and create the following to make a good 12 track 1CD Best Of that covers the iffy noodling period 1968-72 (after Syd Barrett and before Dark Side Of the Moon).
"Let There Be More Light" (from Saucerful of Secrets) - 5:38
Not a good song but it does have an interesting bass riff. It's either this or "Set The Controls For The Heart Of The Sun" as I need a song from the underwhelming Saucerful of Secrets album. "Set The Controls" is a well regarded song but it's already available on the Echoes 2CD Best Of.
"The Nile Song" (from More or Relics) - 3:26
A very enjoyable thrashing heavy metal track. Has high curiosity value and it's one of the few genuinely good songs they recorded during this era.
"Cymbaline" (from More) - 4:50
A good song. Interesting lyrics.
"Green Is the Colour" (from More) - 2:58
Nothing remarkable and it's only here for the sake of it. More is an overlooked album so this track is probably rarely heard by even fans of this period.
"Careful with That Axe, Eugene" (Live) (from Ummagumma) - 8:50
A fan favourite. This live recording is much better than the studio version available on the Relics compilation. Also has the added bonus of getting a song from the Ummagumma live disc onto this Best Of.
"Grantchester Meadows" (from Ummagumma) - 5:53 (Remove the sound effects from the start and end using a utility such as MP3 Direct Cut)
It's only here as I want one track to cover the Ummagumma studio album. This is the best track (in fact it's the only option) from a bad collection of "songs".
"Fat Old Sun" (from Atom Heart Mother) - 5:24
A fan favourite and Gilmour talks highly of it. Gilmour said it was a companion piece to "Grantchester Meadows" so they have been sequenced back to back.
"If" (from Atom Heart Mother) - 4:31
An okay song; and the lyrics deal with madness so it points the way towards Dark Side Of The Moon.
"Echoes" (full length version from Meddle) - 23:43
"Echoes" covers the Meddle album so extensively that more songs from that album are not needed.
"Wot's... Uh the Deal" (from Obscured by Clouds) - 5:08
The Obscured by Clouds album is pretty decent and has a quite a few good songs on it. This has a nice piano riff on it that is untypical of Pink Floyd.
"The Gold It's in the..." (from Obscured by Clouds) - 3:07
A good rock song.
"Free Four" (from Obscured by Clouds) - 4:15
A very good song and the lyrics deal with madness, war and the passage of time; making it the perfect closing track as it points the listener towards Dark Side Of The Moon which is the next album they recorded.
