Jupiter Research has identified differences in the way teenage boys and girls deal with digital music.

A survey of 1,800 US-based, internet-savvy teenagers showed that girls spend 15 percent more on music than boys and are bigger digital music users, except for downloading and burning CDs.

Almost half the sample group of 13 to 17-year-old teenage girls spend over US$100 (about £60) each year on music. Boys are more likely to download and burn CDs, however.

Jupiter Research associate analyst Juliana Deeks said: "Besides their spending, another thing that makes teen girls a particularly attractive market is their reliance on the internet to gather music-related information.

"Nearly half read about musicians or bands online. Girls are also more likely to use the web to listen to streamed song samples and watch music videos and are twice as likely as boys to research concert and tour information online", says Deeks.

Deeks says the Jupiter survey found that "the only online music activities that boys are more apt to participate in than girls are downloading music and burning CDs".

Teenagers were found to be more influenced by recommendations from their friends and music videos seen on TV than by price.

The research also looks at people in the teenage peer group who are turned to for advice on music. Jupiter vice-president David Card said "These music influencers also tend to be girls and they spend 28 percent more on music than the average teen.

"While the music influencers burn and download more than average teens, they also tend to have a broader interest in style and pop culture and are heavier users of online media sites, instant messaging and weblogs".
