When I was a kid, I thought that Britney Spears was the original recording artist of the song (I Can't Get No) Satisfaction; but, it wasn't until about 10 years ago when I found out that The Rolling Stones had recorded it originally back in 1965.
That was the one time I had felt so stupid. Once I had heard The Rolling Stones version of the song, I liked it much better, even though, I grew up listening to Britney's Spears' version.
