Apple is now aiming for a revamp of its Beats Music streaming service, which will see the offering tied in more closely to both iTunes and other Apple products and services, to happen in June -- right around the time of the expected Worldwide Developers Conference, which is likely to happen on June 8–12, according to sources familiar with current plans. In addition to retaining the personalization and hand-curated recommendation features, Apple may be planning to lower the monthly cost.
