HyperSpaces is a free application for the Macintosh. It's a kind of a cross between internet radio and a music player, with a lot of other useful features. HyperSpaces is designed to be both an internet radio and music player at the same time. If you have used any music player on the Mac before, you will know how nice it is to be able to search for and play music, without having to open up your music player to do so.
HyperSpaces can be downloaded free of charge. It is a freeware, meaning that anyone can use it will not cost them anything. It's also possible to purchase a CD version of HyperSpaces. This is not really a freebie at all, but it's a fair price for what is essentially an app that plays music and lets you browse the internet in the same time. HyperSpaces also has support for a number of streaming services such as YouTube, Spotify, Megastore and others. There is also an option to download tracks for use in your own music.
The only downside to the free version is that it's a little clunky and slow, but it's still a great app and worth downloading. If you are looking for a different application, I would recommend you downloading a full version of iTunes on the Mac. However, if you download HyperSpaces, it will still work just fine and you can enjoy a lot of features that iTunes doesn't have.
