The Kindle Fire HD gives you access to Amazon's extensive library of not just eBooks, but also video and music.

Amazon has sold MP3s alongside CDs for a long time now, and there are 20 million songs in the MP3 music store.

Like Apple's iTunes Match, Amazon's forthcoming Cloud Player (which will launch at the same time as the Fire HD) means you can import your music to the cloud and download any of your collection to your Kindle Fire HD. This means you're only partially limited by the internal storage: you simply remove the music you don't want to listen to, it stays in the cloud, and you can download it again when you want it back again. The only snag is that, while your Amazon music purchased are stored free of charge, only the first 250 songs of your own collection can be uploaded before you have to pay. See too.
