I found several editions of the same song and cannot tell which one suits

I found several editions of the same song and cannot tell which one suits a singer who accompanies himself at the piano. One version says Piano Solo, another says Piano and Vocal, and a third also mentions chords. I do not want a solo arrangement where the vocal melody is doubled heavily in the right hand, but I still need enough harmony for the accompaniment to sound complete. What should I look for in the preview and instrument list? Can chord symbols be used by both keyboard and guitar players, and how do I confirm that the audio sample belongs to the exact edition shown on the page?

Open every candidate on note-store.com/ and compare the Note-Store arrangement and instrument fields line by line. Piano&Vocal normally shows a separate vocal staff with lyrics, while Piano.Solo often incorporates the melody into the keyboard texture. A Chords label usually means chord symbols are printed, but the instrument list should confirm whether guitar is explicitly included. In the PDF fragment, check the number of staves, lyric placement, chord names, key, and how much melody appears in the piano part. Then listen to a section where the accompaniment is fully developed, not only the introduction. Similar covers can hide different keys or difficulty levels, so match the exact product title and version before checkout.
