Spotify and Napster

Spotify and Napster are online music streaming services. Anyone can listen to songs from a huge library of music for free. This means a lot of people will be able to listen to music when they might not have been able to before.
Napster was initially released in 1999, and Spotify was founded in 2006. These are both relatively new in the scheme of things, and have created a whole new way of listening to music.
There are advertisements and customers can pay to remove them, but if they are happy to keep them on the page, then the whole service costs them nothing, which could be quite controversial in the music industry, as it reduces the amount of people who would have in the past, paid money for the songs they wanted to listen to, meaning a cut in artists sales and money made.

As well as playing individual songs, these services go a step further, and show you what else you might want to listen to, other similar artists, and pre-made radio stations. This could be good for the music industry, as it is promoting other artists that you may not have considered before, meaning they get more fans, and more people going to their gigs, or buying merchandise and so on.
