We’ve covered Pandora’s troubles before here on BGR and while the custom internet radio provider struggles to strike a workable deal with the RIAA, subscriptions just aren’t covering the bills apparently. Pandora, for those unaware, is a fantastic streaming music service that creates custom stations based on the tonal qualities of songs in its extensive catalog. By way of Twitter, Pandora clarified the fact that it has implemented audio ads in its guest streams. In other words, non-paying Pandora users may hear audio advertisements while subscribers ($36/year) will continue to enjoy unlimited music without interruption. No, we’re not talking about anything close to terrestrial radio’s music to ad ratio of 1:1 or worse – just a quick word from a sponsor every now and then. The move is a logical one of course, and we wouldn’t be surprised if Pandora ends up increasing its subscription charges as well. Users happy about the addition of audio commercials can send thank you notes directly to SoundExchange and the RIAA. Those of you unhappy about the news, will it stop you from using the service – or push you to subscribe?
