"Losing My Edge" is the debut single by American band LCD Soundsystem. It was released as a 12-inch single on July 8, 2002, through DFA Records. It was later featured on the CD version of their eponymous debut studio album. "Losing My Edge" peaked at number 115 on the UK Singles Chart. It was also listed at number 13 on Pitchfork's Top 500 Songs of the 2000s list. In October 2011, NME placed it at number 40 on its "150 Best Tracks of the Past 15 Years" list.

In an interview with the music site "ireallylovemusic", James Murphy (the leader of the group) explained his inspiration for the song:

When I was DJing, playing Can, Liquid Liquid, ESG, all that kind of stuff, I became kind of cool for a moment, which was a total anomaly. And when I heard other DJs playing similar music I was like: 'Fuck! I'm out of a job! These are my records!' But it was like someone had crept into my brain and said all these words that I hate. Did I make the records? Did I fuck! So, I started becoming horrified by my own attitude. I had this moment of glory though. People would use me to DJ just to get them cool. They'd be like 'It's the cool rock disco guy' and this was really weird. And to be honest I was afraid that this new found coolness was going to go away and that's where 'Losing My Edge' comes from. It is about being horrified by my own silliness. And then it became a wider thing about people who grip onto other people's creations like they are their own. There is a lot of pathos in that character though because it's born out of inadequacy and love.

In another interview, Murphy elaborated further on the birth and the release of the song:

So I started going to different types of things and meeting different people, and started throwing parties. And all of a sudden, I was kind of cool, I'd always just been a total... not even an outsider, just sort of a nobody, a sort of invisible, sad and kind of shy. And all of a sudden I was DJing, and felt cool, throwing parties. And then one night I went to go see a band, and somebody else was playing the records that I was playing. Nobody else was playing the records that I was playing, that was sort of my thing! And I got really mad, and I got really defensive. And I was like 'What the heck, that's mine! What the--who the hell is this? Some 22-year-old...', and I got really embarassed [sic?] by being like 'These aren't your records, you didn't write them, you just... play them, you just own them, you can't be proud of yourself for owning them' but I was mad at the same time because I was like 'I know that kid was at one of my parties...'. It was this really dense conflict that I couldn't resolve, and that's where 'Losing My Edge' came from. I didn't have a good answer. I was angry, but I was also pathetic for being angry. There wasn't really a right or wrong, you know? I was right and wrong, and this kid was right and wrong, and everybody there was right and wrong. It felt really dense, and really easy to write from. Easy to make something from.
