The integration of Pandora's (P +6.6%) service with in-car stereos from 23 automotive brands and 8 aftermarket vendors has led to 2.5M+ service activations, the company announces in a PR giving a lift to shares. Pandora also estimates over 1/3 of 2013 new U.S. car sales, courtesy of 100+ vehicle models, will have its service built-in. The debate over how much Pandora's rapid auto market growth affects Sirius XM (SIRI +0.5%) remains intense. Fast-growing mobile radio app developer TuneIn is also making an automotive push; Apple could do the same via iTunes Radio and its automaker deals.
