Does anyone understand why there can be so many versions of a song. Here is an example. I was wanting to download the "we are young" song from itunes. I couldn't remember the name and searched under "tonight". It pulled up a pile of songs. Two were titled "we are young" which reminded me that was the right title. I clicked the preview play button and they played part of the chorus, which sounded correct. So I downloaded it. Well, when I listen to the whole song, I realize that this isn't the same artist. I didn't think it was an older song and when I looked it up with the correct title, I found more than one version--all from 2012. Now, doesn't the original artist have some sort of copyright? The other versions are not that far off from the original. This is frustrating because I am not "into" music all that much, but now feel that I have to be in order to get the songs I want.
