Roku is best known for its connected set-top boxes for TVs, which provide a range of digital entertainment services. More recently it’s launched the Roku Streaming Stick – a USB key that plugs into HDTVs to do a similar job. Anyway, Roku just got more musical with a pair of deals with big digital services: Spotify and Vevo. Both have launched channels for people to access their services on TVs with Roku devices plugged in. Spotify’s channel is available in the US and UK, while Vevo’s is in the US, UK, Canada and Ireland. It’s another small step for each service in their wider TV ambitions, which encompass deals with console manufacturers, telcos and other device makers.
