Top 3 Audio and Video Playable Search Engines You Should Know

these search engines are growing up from offering classic search results to more social media navigator application.
my top 3 playable search engines are today:
1. SkreemR Mp3 Search - currently index over 6 million mp3 files
2. SeeqPod Playable Search and Crawler - SeeqPod's future of search is a system uses a biomimetic approach to discover
3. Tagoo - media search engine (new) - Tagoo's widget called Tagoo Moody is a little embeded "radio" that plays music that is according to your mood... (it seems that tagoo uses skreemr api to resolve. but iam not quite sure.)
2 funny music mashups:
Bloc Party vs. Coldplay - Hunting For Witches...
Copycat - Knowing the Rhythm is Right (Nelly Furtado vs. ABBA vs. Sagi Rei)
