I would say that listening to songs would be something good to practice your hearing Japanese pronounciation, but it's not all since even in songs you can't learn everything (sometimes they change the sound and everything so... yeah, you'll need to find something else to complete)
I once found a nice website for pronounciation of various languages, so I might be able to refer it if I find it again... AH HA! Found it.
Japanese: Vocabulary Guide | 日本語: ボキャブラリー・ガイド
You choose a category and after you can hear what it's supposed to sound like, pronounced by a Japanese^^ You need a plugin though, but I hope this will help! And for dokushuu (which is self-study), good luck! And if I can give you some other advice: don't take too seriously what you hear in anime, you can't learn good japanese in there, so make your own speech style, don't copy it from animes, I heard that from my master often enough^^
I know there is also softwares that play pronounciations and then you repeat and they like "hear" you and show you if you were great of wrong... but I can't remember the softwares name... sorry. I hope I helped a little.
がんばってね！
