Yeah, it drives me nuts too. I downloaded a track labelled "I hear you knocking" by Joe Walsh ? Thinking it was Joe doing a cover of the old Dave Edmonds song.
Doh!
It was and still is The old Dave Edmonds track, which some dork has incorrectly named. I can see how they made the error. Edmonds' voice sounds a bit like Joe and he is playing slide on the track.
It is pretty irritating though when you think you've discovered some rare version of an old song and it's just the same old song.
Renaming it won't change much, will it? Since there are probably millions of copies of the uncorrectly named tune all over the planet.
