Streaming music service Rdio today announced that it will upgrade its entire library of music to AAC audio files, which offer a higher quality of sound than MP3. The move marks the first time Rdio is giving users more control over the sound quality while listening to songs on mobile devices as well as desktops and home audio systems. In this case, Rdio is giving users four different options for sound quality, which can be adjusted to fit your preference based on your device and Internet connection. 

The cool kids like the quality of their music turned up all the way to 320 kbps (the coolest ones prefer lossless), but that’s a luxury that goes away with streaming music over the Internet. Rdio says it’s had enough with that lower quality crap (I can’t really tell the difference, but the cool kids tell me that stuff’s awful), so it is bringing in the ability to stream and download songs at 320 kbps over both Wi-Fi and a cellular connection. If you want to hit this level of quality, you will have to become a paying customer, which will cost $9.99 a month (lame, I know). Rdio has also transitioned its entire library of tracks over to AAC (you know, the format the hip kids use). You can check out the press release below for more information, but I’ve been told only weird people read them.
