The only foreign language i have was just some Naruto openings AND endings that i like.

Every MP3 I have in my music library is of a foreign language except 1 of the Kingdom Heart games OP track which I also have Japanese so what my library consists of pretty much just OP/ED Singles from any of the Anime I have at least watched & any game I was lucky enough to find 1 for along with any other tracks in the album/single I happen to like enough...

Some of them are as followed;

1. "Jonestsu My Soul" by Surface / Naruto Shippuuden ED5 Single - Sunao no Niji

2. "LIFEsize" by UVERworld / BUGRIGHT

3. "Word of the Voice" by FLOW / Persona Trinity Soul OP2 Single - Word of the Voice

4. "Winter Hot Music" by Yui / Bleach OP5 Single - Rolling Star

5. "Boys Don't Cry" by Kelun / Bleach OP8 Single - Chu-Bura

6. "Hanamuke no Melody" & "Ai no Hoshi" by Jyukai / Ah! My Goddess OP2 Single - Ai no Hoshi(? not sure of the album name...)

I will pretty much listen to any J-Music once I guess, favorite artist include FLOW, UVERworld, Jyukai & Takahashi Hitomi...

Yeah, some Naruto songs and Numa Numa.

I have a few on my iPod, Ma Ya Hi (Numa Numa), CaramellDansen, & Hare Hare Yukai.

I have a couple of CDs by Japanese bands, and a few songs in Spanish, but beyond that it's all pretty much English. Most of it comes from anime openings and endings, but a few are bands I just started listening too or something.

I don't have an MP3 player ":O" but I do have some foreign language CDs. Well, two of them. They are Sigur Ros's Takk... (Icelandic) and a DJ Sharpnel album (mostly Japanese). I've also got plenty of Polish stuff but that's my native language so I will not post.

I have German songs by Rammstein that are really good.

My native language is German, but I live in Canada so the majority of the songs are English.

Hellsing world with out logos (full), Gundam suit 00 opening daybreakers bell, and gudam suit 00 opening 3

I have a whole playlist on my i-pod for all my favorite Japanese songs (I'm English), most of them are from Anime shows that i've seen or are from the Kingdom Heart series.

~ "My Will" (dream)
~ "Fukaimori" (Do As Infinity)
~ "Song of Truth" (Do As Infinity)
~ "Dearest" (Ayumi Hamasaki)
~ "Every Heart" (BoA)
~ "Come" (Nami Amuro)
~ "Hand In Hand" (dream)
~ "Passion" (Utada Hikaru)
~ "Hikari" (Utada Hikaru)

My original language is English, but these two songs I like-

Cherish- Ai Otsuka(Japanese)

Jai Ho- [forget the artist name]- (some Indian Language, I forget)

The only songs I have with non-English vocals are either Spanish, Swedish, or Japanese. The number of Spanish and Swedish tracks are negligible, to be honest, but the Japanese tracks make up a noticeable portion of my music.

My playlist of songs with Japanese vocals currently has over 250 songs in it. The majority of those are admittedly related to an anime or visual novel. Not included in that, I also have hundreds more instrumental sound track pieces related to Japanese works (such as Air, Clannad, Angel Beats!), as well as over 400 Final Fantasy tracks.

Despite that, the majority of my library is still in English, with 60's-80's rock dominating the competition.

I have 3 Rammstein songs on my iPod. I'm American and Rammstein are German.

I'm from Brazil, so I speak Portuguese. Despite that, I don't hear a lot of regional music (honestly anything). So all music that I hear are in a foreign language. But if I don't count the English songs (the majority) I have musics in:
- Finnish - Kuolema Tekee Taiteilija and Erämaan Viimeinen, Nightwish;
- Italian - Herr Mannelig, Haggard;
- Latin - Some musics of Krypteria;
- Irish - Some musics of Celtic Woman.

I know I have some music in another language but I can't remember now.

Got a few songs in foreign languages. My home tongue is English/ Afrikaans

1. Angel - Shweta Pandit (Hindi)
2. Why this Kolaveri Di - Dhanush (tanglish -Tamil/English)
3. Live My Life - can't remember artist name
4. Siya Gidha - Dj Cleo
5. Jezebel - can't remember artist name

Like some of you said, i havee Naruto openings and endings and i have some Kingdom Hearts songs.

I have all the Beatles songs that they did in German. Eventually I'll also have Caramelldansen on there for kicks.

I have 93 foreign language songs. (I'm french )

Yeah, they did I Want To Hold Your Hand (Komm, Gib Mir Deine Hand), She Loves You (Sie Liebt Dich), and maybe more, don't remember off the top of my head.

Eternal Snow, Imitation Black, Soundless Voice, iconoclast, Love Distance Long Affair, EGOMAMA, Sunadokei, Love so Blue... yeah, that's about it.
