Also, an embedded Grooveshark playlist app is coming into existence, and will be placed on my sidebar, probably near the top. It will likely feature a rotating playlist of songs I enjoy listening to at the moment.
To get the Grooveshark embedded playlist add-on, you will need to create a Grooveshark account, then create a playlist of your favorite music (double check the songs, as occasionally you may find multiple versions of the same song), and then click on the "i" button next to your new playlist. From there you should see the "Embed Playlist" button. That will take you to an in depth embedded player creation, where you can customize the size, colors, and more of your special Grooveshark embedded player app. After all that is over with, you will get the code which you can then paste into your Blog's sidebar.
And if you want some cool background, then hopefully you can find something with a Google Search for Blogger templates
As always, cool stuff!
