Getting the design just right is reportedly causing the delay for YouTube’s planned music subscription service, according to Billboard. The music magazine and website cited an interview with an unnamed executive who knows of YouTube’s plans that the service will launch in the “second quarter or beyond” instead of a launch earlier in the year. The executives reportedly want the offering to be compelling as soon as it launches and not be eased out as a beta and improved over time, which Google usually does with its products. So, if you’ve been dying to see what it looks like, you will have to wait a bit more.
