If you're on the hunt for chords to 'Stuck With You', there are a few reliable places I always check first. Ultimate Guitar tends to be the go-to — search with the song title plus the artist (for example 'Stuck With You' Huey Lewis) so you don't end up with the pop duet 'Stuck with U' by Ariana Grande & Justin Bieber. On Ultimate Guitar you can find multiple user-submitted chord sheets and tabs; pay attention to the star ratings and comments, because people often post better transpositions or capo suggestions in the threads.
I also like using Chordify when I want to hear the progression along with the track; it auto-detects chords from the audio and displays them in time, which is awesome for learning strumming and timing. For official accuracy, Musicnotes and Sheet Music Plus offer paid printed arrangements and PDFs, which are great if you want a faithful piano/guitar score. Songsterr is handy when you want precise tab playback for solo parts.
Beyond sites, YouTube tutorial videos are gold—look for acoustic covers or lessons that show chord diagrams and strumming in real time. If you want a fast tip: try the capo (many versions use one) and compare a few chords versions to pick the voicing that matches the recording. After trying a couple of versions I ended up mixing a chord chart from Ultimate Guitar with a YouTube strumming tutorial, and that hybrid approach got me gig-ready in a weekend.
