Reviews for "Eternal Roamers"
It's not a bad song, but it just needs to be recored internally rather than externally. I'm still wondering how I even get my song onto the list of songs by unscouted artists.
It's a pity this is recorded with external system. As CobaltZ said, try to use instead a video recorded and then turn it to MP3. At least we'll be able to listen to this better!
It seems quite evident that this was recorded using an external microphone. If your software for creating music doesn't provide a way to record your tracks directly, record them with a sound recorder or you can use a video recorder and later turn the video file into an MP3 via a conversion website. The use of an external microphone decimates quality and consistency in volume. If you're confused, just say so.
11/5 from me
