Soundcloud is a music and audio platform that allows users to upload, share, and promote their original content. While Soundcloud itself doesn’t sell promotion, there are many third-party services that offer Soundcloud promotion, such as plays, likes, comments, and reposts, to help boost the visibility and popularity of a track. However, it’s important to note that these services may not always be legitimate and could potentially harm your account, so it’s important to research and choose a reputable provider.
