I asked chatGPT:

Good question. I couldn’t find any 1980s song by a solo female singer with the exact lyric “nothing really matters” (or “nothing truly matters”) that matches your description. Here are a few thoughts and possibilities, plus what might help you narrow it down — and a guess + next steps.

💡 What the Searches Turned Up

1. “Nothing Really Matters” by Madonna — but that’s from 1999, so too late for your 80s vibe. (Wikipedia)

2. “Nothing Really Matters” by Gabrielle Aplin — also way more recent (2019). (Wikipedia)

3. “Nothing Really Matters” by Fiona — this one exists, according to Shazam. (Shazam)

   • But Fiona’s “Nothing Really Matters” seems to be a reggae-style song, not a high-energy 80s disco/funk. (Shazam)

   • Also, Fiona’s own career peaked more in the late ’80s rock/pop space — her album “Beyond the Pale” was in 1986. (Apple Music - Web Player)

4. I found no credible matches for an 80s dance/disco track where a female singer sings exactly “nothing truly matters” (in that phrasing).

✅ My Guess

Based on what you remember, it’s possible the lyric is slightly misheard. The Fiona song looks like the closest title match, but the style doesn’t align well with what you described (if it truly is her song).

🔍 What to Try Next

To track it down more precisely, you can:

• Use a song identifier app (like Shazam or SoundHound) the next time you hear it in a store.

• Ask the store (if they play a fixed playlist) — they might be able to check their in-store music list.

• Try humming the melody into a “hum to search” tool (some modern music apps do that).

• Think about other lyrics or fragments: maybe there’s a line before or after “nothing really matters” that stands out. Even a few more words help a lot.

If you like, I can dig into 80s female disco/pop songs with similar-sounding lyrics (bass line, synth, etc.) and send some top candidates. Do you want me to do that?
