Context paragraphs:
How Come U Don't Call Me Anymore?: "How Come U Don't Call Me Anymore?"  is a song by Prince.  It is a ballad of romantic longing with some gospel elements.  On his original recording of the song, which was released as the non-album B-side to his 1982 single "1999", Prince performs most of the song in his falsetto range, with his own bluesy piano playing providing the only instrumental accompaniment.  The song's first album appearance was on his 1993 compilation "The Hits/The B-Sides".  It was later included on the soundtrack to the 1996 film "Girl 6".  Prince also performs the song on his 2002 live album "One Nite Alone... Live! ".

The Unquiet Grave: "The Unquiet Grave" is an English folk song in which a young man mourns his dead love too hard and prevents her from obtaining peace.  It is thought to date from 1400 and was collected in 1868 by Francis James Child, as Child Ballad number 78.  One of the more common tunes used for the ballad is the same as that used for the English ballad "Dives and Lazarus" and the Irish pub favorite "Star of the County Down".

Still Waiting (Prince song): "Still Waiting" was the third US single from Prince's second album, "Prince".  It was Prince's first ballad to be released as a single and was mildly popular on the R&B chart, reaching #65.  The ballad speaks from the perspective of a young man who hasn't yet found love but yearns for it.  The track is mainly piano, acoustic guitar and synth-based and was often played live with extended instrumental solos and audience teasing.  The song is a more traditional R&B ballad, before Prince established himself with trademark sexual romps like "Do Me, Baby" and "International Lover".

Adore (Prince song): "Adore" is a song by Prince.  It is the last track on his 1987 double album "Sign o' the Times", following the live track "It's Gonna Be a Beautiful Night" (the crowd noise from which bleeds into the beginning of the song).  A long, ornate slow jam featuring Atlanta Bliss and Eric Leeds on horns, it was described by "NME" reviewer Paolo Hewitt as "a sugar ballad that harks back to the Stylistics but is indelibly Prince's, a lush yet remarkable piece of music, and a fitting climax".  It received significant radio play despite never being released as a single, and became an occasional part of Prince's concert repertoire.  A 4:39-long edit of the song appears on the 1993 compilation album "The Hits/The B-Sides", and the "Girl 6" soundtrack album contains the full-length version.  Prince's 2002 box set "One Nite Alone... Live! " includes a solo performance of "Adore" with piano accompaniment.

The Wandering Prince of Troy: "The Wandering Prince of Troy" is an early modern ballad that provides an account of the interactions between Aeneas, the mythical founder of Rome, and Dido, queen of Carthage.  Although the earliest surviving copy of this ballad dates to c. 1630, the records of the Stationers' Register show that it was first licensed to Thomas Colwell for printing nearly seventy years prior in c. 1564 or 1565.  The narrative of the ballad loosely parallels the events in books 1-4 of Virgil's "Aeneid" and the seventh epistle of Ovid's "Heroides". .  Like many ballads from the period, "The Wandering Prince of Troy" was frequently reprinted in broadside format.  Various copies of such broadside facsimiles exist today in multiple libraries: the National Library of Scotland, the British Library, the library at the University of Glasgow, and the library at Magdalene College, Cambridge.  Online facsimiles of the ballad broadsides are also available.
