Two unreleased Whitney Houston songs have appeared on the internet.
The tracks were recorded before Whitney's death by accidental drowning ahead of the Grammy awards in Los Angeles in February, and will also be included on a new greatest hits album.
The tracks are called 'Never Give Up', which was written by Jermaine Dupri, Bryan-Michael Cox and Johnta Austin, and 'I Look To You' - an alternative version of an earlier hit which has been re-recorded as a duet with R. Kelly.
'Never Give Up' has a positive and upbeat message, and includes lyrics such as: "Never, never give up/ Never, never give up/ No matter how many times somebody tells you it ain't working/ Never, never give up.
"Never, never give up/ Hold your head to the sky, look them right in the eyes/ Tell them you will never quit until the day you get it right."
The finances of Whitney's estate are still being worked out, but sales of the new album will help go toward paying back part of a $30-$40 million advance she received for a $100 million record deal signed in 2001.
Whitney's daughter Bobbi Kristina Brown is the sole beneficiary of her mother's estate, and it's executors recently reached an agreement with her over payments.
Under the deal, 19-year-old Bobbi will receive 10%of her mother's wealth when she turns 21, almost 20% at age 25 and the remainder when she turns 30.
