"I Think I'm In Love" is a sickbed lament where frontman Jason Pierce mourns his heartbreak and loneliness. He numbs his pain with heroin but the opiate euphoria won't last and he acknowledges his drug addiction is a disease.
Pierce wrote "I Think I'm In Love" for Ladies and Gentlemen We Are Floating In Space, an album he mainly penned after his girlfriend, the band's keyboard player Kate Radley, left him for The Verve's Richard Ashcroft. However, according to Spiritualized guitarist John Coxon, the song's content is more general than biographical. "There was quite a lot of turmoil within the band at the time, but the lyrics aren't specifically about Jason and his emotional state, Coxon told Uncut magazine. "They're about the human condition. We all have those insecurities."
Pierce added the lyrics after composing the music. "I kind of remember that whole lyric for the end section coming together in one afternoon at Moles Studio," he said. "Once I'd committed to the idea it was quite easy to get everything down."
"I Think I'm in Love" is an 8-minute opus that is half blissed-out space ballad and half focused groove. "We'd been listening to The Beach Boys and The Velvet Underground," Pierce told Uncut, "so the idea that you could take two songs and make one song, it felt like you could do that quite easily. And not two songs that weren't good: two of your best songs. It made sense. It wasn't a leap into the unknown."
Spiritualized released "I Think I'm in Love" as the second single from Ladies and Gentlemen We Are Floating In Space. At 8:10, it was unlikely to be played on the radio, so they cut it down to 3:57. "I definitely had something to do with it, but they don't edit well, these songs," said Pierce. "It's a call: do you want it to go on the radio or not? It wasn't as successful as the full-length track, but no harm done."
NME chose Ladies and Gentlemen We Are Floating in Space as their album of the year for 1997.
