There are plenty of tools around for sharing and listening to music but music creation tools seem to be a bit thin on the ground.

1. Jam Studio - A drag and drop approach to making music. You have a wide selection of instruments and 8 tracks to mix your tune. The one limitation for me is the inability to add a voice. This leaves the online tool with some ground to make up on desktop rivals such as EJay DJ. The songs cannot be downloaded on the free version although a link can be created. Click Here for a quick example.

2.Jamglue - This is a remixing tool. You can upload music or record your own. There is a collection of tracks to add to your mix provided by other uses.

3.Bojam - This site hoped to do for music what wikipedia did for text.

4. Last FM - While not a music creation tool I like this one so much that I think it is worth sharing. It is basically an online radio. You can put in an artist or a track and listen to the song 3 times for free. After this you would have to pay for the song. You can choose to listen to similar artists and the radio will play for ever, a good way to be introduced to new music.

5. BBC Virtual Studio - An online tool to allow you to create your own mixes. There are over 1000 samples to play with on this 4 track mixer.
