That would be copyright infringement if the original song was protected.
You can only copyright a song if you are the song's author. You can't copyright someone else's song. Although the author can sell you their copyright.

Each song has its own copyright year.
Singing a song in private for personal enjoyment is not considered copyright infringement. However, performing a song in public or recording and distributing it without permission from the copyright holder may be considered infringement.
It is probably copyright infringement. There are exceptions, though.
The only way to be certain is to contact the copyright holder yourself.
If you are not the composer of the song then you can NEVER take the copyright as yours; you would have to purchase it from the copyright owners. Also, when the copyright expires, 50 or more years after the author's death (or after publication, depending upon circumstances and national laws) it is no longer copyrighted at all and nobody can possibly own the copyright.
