Actually I have uploaded my piano cover for nano.RIPE's "Tsukihana" (月花) to my Soundcloud earlier so the cover could be found there in my Soundcloud, as well as the download link (if you can't download it, then the download count must have reached the limit so please inform me so I can upload it to Dropbox). I uploaded two versions: the TV version and the full song version. I'm glad to know that the play number for both covers have reached ein tausand something plays.
PS: THE LINK IS NOT WORKING ANYMORE. Sadly I have to say that my Soundcloud post was reported and I couldn't retrieve back my track. That is really annoying because that's my own piano cover and I didn't steal anyone's music.
