youtube Music 在這幾天正式上線，雖然相較其他音樂服務真的晚很多，但是卻不會是一個阻礙 Youtube 發展的絆腳石，除了已經有非常強大的音樂資料庫之外，用戶的數量也早就不是其他平臺可以較勁的，而且還有像是 Live 版、惡搞版和混音版各式各樣的版本可以收聽，光想就覺得這個對手根本有課金！（最近手游玩很多...） Youtube Music 也不意外的會在音樂轉場期間播放廣告，要用付費的方式才能移除這些穿插廣告，而且付費后就可以離線收聽、背景播放；其實到現在看過比較過 Apple Music、Spotify（在臺灣則是 KKBOX 為龍頭）這些串流音樂服務之后，能提供的服務落差著實不大，完全看使用者喜歡什么類型的音樂，哪一間能提供最多該類型的音樂以及適合的價格，在這場和平之爭中用戶也許可以成為漁翁。 -- 一張圖就能看到今天最重要新聞，這么好康，不按贊嗎？ 請幫討喜小姐按贊：facebook/miluson.lu --看更多攪豬屎練肖話的 今日新聞淺談 傳送門 討喜小姐粉絲團
