slackerChange is in the air for North American streaming radio service Slacker Radio, with representatives tipping tech site SlashGear off about an imminent ‘major overhaul’ in order to ‘better compete with Spotify and other popular music-streaming services’.

Specific details are thin on the ground, but the article suggests Slacker will be ‘refocusing’ its efforts, and that ‘the redesign and restructuring will be completely different than what the service is currently all about’.

Which points to a relaunch as a full on-demand streaming service with a free tier – risky in what’s already a crowded market – or perhaps a shift towards more of a Songza-style mood-music radio service.

While Slacker has added new features regularly over the past couple of years, it’s never looked in danger of challenging Pandora as the top dog in its current category.
