iTunes Lets You See Previews Without the Download
Apple has launched iTunes Preview, which is a means of showing what music is available on iTunes right in the web browser. This seems like an incredibly obvious way to do it, and one that many have been waiting for way too long, but now if you want to look at the iTunes catalog, without having to install iTunes, you can do so.
You can’t listen to song previews without installing iTunes, but at least you can see what they have. You do still have to download iTunes to purchase music.
According to MacWorld, the feature only works for music, but could probably be applied to video at some point. The feature can be accessed at the iTunes Charts page or clicking on a link from the music store.
When you go to a preview page, you can see information for the album like the track listing, the length, and the price. There are also reviews that you can read through.
If you go to the Charts page, you can search for other artists and songs and get to preview pages for those results. However, if you click on the link on the search results page that says "view more results in iTunes," it will take you to the iTunes download page (assuming you don’t have it installed).
