This program looks quite cool – Spotify.
It’s a small program that’s free. You install it on your PC and it allows you to search for music online and listen to it (with a occasional adverts). Best thing of all, it lets you share your music (including any music you have on your PC already) with friends who also have Spotify and via Facebook and/or Twitter.
If you don’t like the occasional short ads, you can upgrade – for a price – to an ‘ad-free’ version.
Sounds like this has lots of potential – I’m off to play!
