It sounds like you're going about this the wrong way. If you want to change the UI an Activity contains, then Fragments would be the better approach. There's a bit of a learning curve there, but it's good android design, and well documented.

Further, you seem to be confusing formatting and content. If you're displaying song lyrics, you don't need a new layout for each song. You just need to change the lyrics and keep them in the same activity. What you're doing is akin to creating a new web-browser for each web-page you intend to visit. Instead, find a way to store the lyrics and display them on a single activity (or in a fragment) to display those lyrics. The same would apply to each album: One activity would display the album cover in the corner (or as background), the title, release date, etc, as text, and then a list of songs below. The actual content of the TextViews can change, but the layout ought to be the same.
