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.
Yes, you can potentially be subject to copyright infringement if you perform a copyrighted song without permission.
It would be a copyright infringement if the advertiser has not paid for the use of the song. Advertisers generally do pay, because they wouldn't want the bad publicity of a court case.
I'm sure there are ways, but this is considered copyright infringement and can lead to big fines and even jail time if caught using the music.
That would be copyright infringement if the original song was protected.
It is probably copyright infringement. There are exceptions, though.
No. That is copyright infringement.
No.
It depends upon whether you have permission, or need permission for your use. Some limited uses are perfectly legal, but you have the burden of proving that your use qualifies for the statutory exemption (e.g., singing it for free in public). If you used a song without permission from the rightsholders, you would be guilty of copyright infringement. Statutory fines in the US range from $750 to $30,000. If the copyright was registered in the US Copyright Office prior to the infringement, the statutory damages could run as high as $150,000 for each song. It is also a federal crime to use a willful copyright infringement for commercial advantage or private financial gain.
Yes, although if your song follows the storyline of the book too closely, it might be considered a derivative work, which would require a license.
Without a license, yes. That is assuming you did not personally compose, perform and record the song yourself, or take a public domain composition and perform and record it yourself, either of which would mean you own the copyright on those recordings and it would not be copyright infringement to use the recording of the song any way you like.
Yes; public performance is one of the exclusive rights of the copyright holder--when sheet music says "all rights reserved" on the bottom, that's exactly what they mean.
No, the song Drunk drunk again is not in the public domain because of the copyright infringement issues.
