Looking to stream tunes based on your mood without the need to make a meticulous selection? If so, iHeartRadio is looking to oblige. The internet music service has announced the “Perfect For” feature that allows you to tailor your stream from over 1,500 live stations by selecting your current temperament or activity. Following the announcement at CES today, the add-on will be available for iPhone and PC with compatibility for other devices arriving shortly. In addition to the listening tool, the outfit has added alarm functionality for early morning wake-up calls and reminders to keep your schedule in check. This means that your tunes on those difficult Monday mornings can now reflect just how awful the end of the weekend really is.
