choosing between two different languages

I'm having trouble choosing a language to learn.  I've decided on either Russian or Swedish.  Here's why...

Russian: my friend is learning Russian (albeit at a slow pace).  It'd be kind of neat if we could talk to each other in a language other than our native English.

Swedish: it sounds really pretty when spoken, and if I were to learn it, it would be the first foreign language I will have become fluent in.


Those are my reasons, now here are my previous language-learning experiences.  I know a little bit of French from a 1-year (so far) French class I've had.  I plan on continuing the class next year.
I also have a rudimentary knowledge of Japanese.  I can understand the pronunciation and I know some basic phrases.  I can read hiragana and a few katakana, and I know one or two kanji.


Sorry for the long post, but I am trying to decide carefully so I won't regret my decision (or get bored and give up) later.

Japanese being hard is a myth, it might even be easier than English. The only real difficulty is the writing system. I say difficulty, but it's just a time consuming task.
