"One of These Days" is the opening track from Pink Floyd's 1971 album Meddle. Save for the spoken line "One of these days, I'm going to cut you into little pieces" the song is instrumental and features double-tracked bass guitars played by David Gilmour and Roger Waters. One of the two bass guitars sounds quite muted and dull compared to the other. According to Gilmour, this is because that particular instrument had old strings on it, and the roadie they had sent to get new strings for it preferred to wander off and see his girlfriend instead.
The track opens with a "wind sound" emulated by means of a delayed wind drum slowed down to half speed. The ending solo on the left speaker is David Gilmour playing a regular guitar solo dueling with himself, via multi-tracking, playing slide on right speaker. At approximately 3:03 minutes into the song, a similar sound is heard to the theme tune of the popular science fiction television series Doctor Who. Strangely enough, in the music video/concert visuals for the live tour a visual similar to the title sequence is also seen
The threat, a rare vocal contribution by Nick Mason, was recorded through a ring modulator and slowed down to create an eerie effect. It was aimed at Sir Jimmy Young, the then BBC Radio 1 and Radio 2 DJ whom the band supposedly disliked because of his tendency to babble. During early 1970s concerts, they sometimes played a sound collage of clips from Young's radio show that was edited to sound completely nonsensical, thus figuratively "cutting him into little pieces". The bootleg compilation A Treeful of Secrets contains a demo version of "One of These Days" in which the Jimmy Young collage loops in the background during the song. However, the authenticity of this demo has not been confirmed.
According to John Peel, Waters has described "One of These Days" as a "poignant appraisal of the contemporary social situation". Gilmour has stated that he considers the song the most collaborative piece ever produced by the group.
It was resurrected for the group's 1987/1988/1989 A Momentary Lapse of Reason world tour and 1994 The Division Bell tour. It was included on the "Delicate Sound of Thunder" and "Pulse" albums and videos released respectively in 1988 and 1995, performed by David Gilmour on lap steel guitar, Tim Renwick on rhythm guitar, Guy Pratt on bass, Rick Wright and Jon Carin on keyboards, Nick Mason and Gary Wallis on drums and percussion. The only difference between the original track and the 1988/1995 versions is the addition of a wah-wah effect during the picked delayed bass solo in the middle of the track and a long melodic slap riff between the intro and the main delayed slap bass parts, as well as an additional rhythm guitar part from touring guitarist Tim Renwick.

Another promo video was used to promote Delicate Sound of Thunder and got brief airing on MTV in 1989. It showed the band performing the track on stage and shots of the inflatable pig that flew over the audience during the song in the show. The end of the clip blacks out instead of segueing into "Time" like on the Delicate Sound of Thunder video.
