lol why don't you just whistle it yourself and save us the drama? but fine, I'll bite. maybe try 'The Walker' by Fitz and The Tantrums – if you're actually looking for the song and not just trolling us yourself :P

Songs with whistling are dime a dozen. But if it's an indie vibe from a few years back it could be 'Fitzpleasure' by alt-J. They're more alternative than indie per se, but hey, might be what you're scratching at in your brain.

ooo i know this! It’s '5 Years Time' by Noah and the Whale I bet. Super catchy and whistly.

Indie. Whistling. Commercial. Are we just describing every song since 2010? But seriously, try 'Let Her Go' by Passenger, if you want to be sad and pensive while reliving whatever product it was selling.

OK there's a few that come to mind with whistling cause it's my jam lol. Check these out just in case: 'Jealous (I Ain't With It)' by Chromeo, 'Tighten Up' by The Black Keys, 'Two Of Us' by The Beatles, and 'Wind of Change' by Scorpions. The indie/alter vibe makes me lean towards 'Tighten Up' though.

That's gotta be 'Pumped Up Kicks' by Foster The People. Classic whistle hook, can't miss it. Big hit and was all over the place tv show-wise and commercial-wise if we're thinking of the same one.

hmm indie whistling song?? maybe 'Home' by Edward Sharpe & The Magnetic Zeros, that has a bit of a whistle thing going on, iirc

Hey, it sounds like you might be talking about 'Young Folks' by Peter Bjorn and John. That song was pretty big some years ago and has that catchy whistling right at the start. Was used in like a bunch of ads and stuff too.

I found it, it's Harlem Globetrotters theme song.

"Traveling around the world, and coming home again..."
