Yesterday her song had been played so many times it jumped to number nine on the website's chart.
A Facebook site called "RIP JESS LAW" has been created by her friend Yasmine Rigby as a tribute and yesterday the site had more than 500 fans.
Jessica Law's talent as a singer and songwriter is mentioned on the site several times.
She performed in the Central Otago gold-rush musical Rush in 2005, and was a finalist in the National MLT Songwriting Awards in 2007, and was working on songs for her debut album.
A memorial service will be held for Jessica tomorrow.
In the crash, which happened near Arthur's Point, Jessica had been travelling as a passenger in a Nissan Pulsar with Jesse Boulay (16) and Josephine Clay (16), who were both airlifted to hospital with serious injuries.
Josephine was reported to be in a stable condition in Southland Hospital yesterday while Jesse remained in a critical condition in intensive care in Dunedin Hospital, according to a hospital spokesperson.
According to previous statements from the police, the teenagers' car crossed the centre line and collided with a Mercedes driven by a Queenstown woman.
The woman and her two children were all taken to Lakes District Hospital with minor injuries.
Sgt Duffy said they had since been discharged from hospital.
