well, my sister told me I could visit and do some research about it, and well, they're available at mostly Japanese sites, some songs are hard to find though, I watched some on YouTube, but I have the soundtracks of Pub and GO!, Mein Gott, and Absolutely Invincible British Gentleman.

I have almost all of the songs possible from hetalia. If আপনি don't want to research a lot, then look at my VERY long answer.
Audio.isg.si. আপনি don't need to be a member and they have everything from Maru Kaite Chikyuu (even though আপনি don't need that...), Hatafutte Parade, and all the Character Songs like Carrot and Sticks and With Love, From Iceland. There are also Fanmade songs.
Type in ইউটিউব to mp3 and when আপনি are at a song আপনি want on youtube, just right click the box where the song is and press copy video লিঙ্ক অথবা something and go back to the ইউটিউব to mp3 page and right click again and press paste then it will say convert video. Press that button and when the picture of the video shows up, press the word download and then আপনি have the songs আপনি want. Also, আপনি might want to have ইউটিউব and the ইউটিউব to mp3 of different tabs. Also, sorry that it was like a summary.
