Update New: Freezing and hanging has been mostly resolved. However, local songs have forever been a PITA to deal with and nothing has changed in the years. I follow the steps recommended by Spotify and still would get inconsistent results. Update Old: Freezing and hanging has gotten worse. Unbearable. Original: It freezes or hangs often enough where it's more than a minor inconvenience but not quite a big problem. And I can't say I'm a big fan of any of the recent updates from an interface perspective. Also, while it's unsurprising that Spotify would be a battery hog when using mobile data, I never expected it to use THIS much battery. By far my phone's biggest offender.
