Music tracks are tricky because they're technically less true to standard grammar/syntax than anime, but when you sift through these issues, they become more valuable learning tools because you can repeat them, they require significant memorization (unlike anime), and they're good for remembering terms (If you need to remember the word for X, you can think of the track that states X and just pretend you're listening to that track).
That said, if you're just starting to learn JP, do not bother with these. Learn the language from scratch and pick these up when you're roughly 2 yrs into the learning process because they'll confuse more than they help before then. The best way to supplement JP lessons is to use online resources (This is especially true if they're using the standard Genki book, which tends to teach terms outside of their grammatical derivation).
