I finally have hardware working the way I like it at home (stereo inputs), at the office and gym (bluetooth headphones), and in the car (aux input or bluetooth to head unit). Now I'm ready to pay for an ad free music streaming app. The problem is deciding which one to get. I've messed around with the free versions of Pandora, Slacker and TuneWiki as well as FlyCast for streaming FM stations. I'm not crazy about the latter two as I prefer to create a customized "station" that plays exactly the music I'm in the mood for. I've also used Grooveshark on the computer, but I have no idea how good the Android app is without a Lite version to test. Pandora, Slacker and Grooveshark charge roughly $3/month for ad-free music. I'm curious to know what others think about the various services, or one I have not mentioned. I don't mind paying for a good app, but I can't justify paying for all of them when one should suffice. So what's your preference? A reason besides "It's the best" would be an added bonus.
