While boasting a large music library is great for the voracious music lover, it can also mean a lot of clutter in terms of CD jewel cases. Downloading music is good because digital files don't take up any physical space. Amassing hundreds or thousands of albums via downloading means a big selection of music, without a big collection of jewel cases and CD racks. An external hard drive can hold the same amount of music as a roomful of CDs.
People often buy CDs for one or two singles, weeding through a bunch of filler to get to the songs they really want to hear. Downloading music makes it possible for you to purchase only the songs you want and avoid the unwanted album filler. Not only does this mean that you will save money buying singles rather than albums, but it means fewer pesky album tracks taking up space in your music library.
Downloading music is much more convenient than driving down to a music store and buying a CD. You can purchase music with just a few clicks of a mouse and have it downloaded to your computer within seconds, with the right Internet connection. For those who don't live within close driving distance of a music store, downloading music makes it possible to purchase the latest music without going to the trouble of paying for gas and traveling long distances.
