seeqpod is like Google for music, with a player that will play the results.
For example, here is a song from my early college days by M.C.L. (Microchip League) called "New York, New York."
That is another cool feature...the ability to "embed" songs in your web site, just like you can do with youtube videos.
You can also embed an entire playlist. Here are some difficult to find songs...
This seems like it is a lawsuit away from being shut down. They claim they are not hosting any music, just pointing you to it (just like Google does) so they aren't doing anything wrong. They go to great lengths on their web site to defend their right to exist.
Just like Napster, I would imagine this site is mainly going to be used to access copyrighted works. Once they start profiting from advertising that is connected to illegal access to copyrighted works, the party is over.
This will be fun to watch. Enjoy it while you can.
