George Jones' catalog is huge, but unfortunately, a lot of it is out of print. Not even streaming sites have his back catalog. But if you just go with compilations of his 50's-90's recordings, you can find many gems.
Joel Whitburn has Jones ranked #2 behind Eddy Arnold on the All Time Country chart list.
This list of my 40 favorite Jones songs is taken from his singles charts. But be on the look out for online postings for his deeper catalog songs.
