iTunes is an Apple software application for playing and managing digital multimedia, such as music, movies, TV shows, audiobooks, and podcasts. Originally released for Mac computers in 2001, iTunes was ported to Microsoft Windows in 2003. iTunes allows users to play, download, and organize their media files, as well as purchase new media from the iTunes Store.
To buy songs from the iTunes Store, you will need an Apple ID and a valid payment method. You can create an Apple ID for free on the Apple website. Once you have an Apple ID, you can sign in to the iTunes Store and browse the available music. To purchase a song, simply click on the price button and follow the prompts to complete your purchase.
