I need a Babel fish, ideally

Here's a question. I get to choose some electives next year right. This has me over the moon because language is as far away from numbers as you can possibly get in this course. So here are my choices:

1. Italian
2. Spanish
3. Russian
4. Japanese
5. Mandarin

If anyone has had any experience learning these at a very basic level, please let me know which one you enjoyed learning. And Tom, don't say Italian, we've already had this conversation and established your biasness. kthxbai.
