top50songs.net is a tool which helps you to find out the top 50 songs of some artist or band, according to Last.fm statistics. All you have to do is write your favorite artist's name in the search box, and press "Get top tracks".
The tool is built on PHP and uses the Last.fm API. For now you can see the list of the top songs and some info for each song. In the future more features will be added, like similar songs or similar artists to your favorite song/artist, album info, lyrics, top albums for artist and more.
