Any Song, From Anywhere, Instantly Edit
Seeqpod

Seeqpod is a new and quite a unique music search engine. The ‘playable search’ engine trawls the web, and finds the song you are looking for from within any source. It then lists all the results within the page, and can be played automatically.

To be noted, as far as I can tell, this is legal in the same way that video link sharing sites are (sites like www.joox.net that do not host any copyrighted material but just build references to where they can be found.) Essentially, you cant share/get music via this service, but it is great for those “Have you heard this song?” moments where you need a song then and there.
