We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget inquiry is coming to us from Katie, who is totally down with the stream. The radio stream. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com.

"Rdio, Spotify, Pandora, Rhapsody -- there are way too many streaming music services out there begging for my money. Which is the one I should spring for? I live in the US, but would love for whatever I choose to work when I travel internationally, if that's possible. Trying to keep it up under $10 per month, and looking for a large library and nice mobile compatibility. Thanks!"

So, streamers -- what's your go-to service? Tried a few of 'em? Let us know which you prefer, and why, down in comments below.
