Is it possible to listen to a track on itunes before buying it?

[scampadoodle]

Am an itunes virgin & just want to check the version of the track I want as there are a few.

You can hear about 30secs of each track - just double click on the track and it should play through your pc / laptop

yeah you just double click on the track you want to hear

or go onto Youtube, and watch the video of the song before you then buy it on i-tunes

Cheers, thanks. Didn't think to double-click
