I once was listening to a song in a cafe in Pakistan and couldn't find it. Me and friends did:

- Shazam a few times

- Ask the restaurant folks if they can look at some screen to get us the name, apparently it was on a screenless mp3 player

- I recorded a sample of it

- I tried all fingerprinting services apart from Shazam

- Posted on a few subreddits, found the base song, a daft punk song but not exact one

- I looked up all remixes all over internet, no luck

- Finally someone found the exact soundcloud link, apparently it was a remix with no mention of daft punk anywhere
