Sometimes, you want to hear a song right this second, and you don't want to futz about hunting it down on Google. TuneCrawl is a web app that searches songs on Spotify, YouTube and Soundcloud so you can start listening right away.
TuneCrawl is great for those "I need to listen to that song now" moments, because it's fast and only shows you songs that are actually playable. When you get the results, you click the play button, and it will play right there in your browser. No messing around with Wikipedia entries, blog posts or anything else.
It should come in handy when you really need to get that horrible song out of your head.
