In another dotfile discovery, I ran across makeitpersonal in Artem's dots. makeitpersonal makes it easy to fetch lyrics in plain text using curl. Naturally, I didn't waste time adding this to rdio-cli. By default, it looks up the current track, but you can override artist or song title, the former being quite useful for covers.
$ rdio current Now playing: That Old Time Feeling / Rodney Crowell / This One's for Him: A Tribute to Guy Clark $ rdio lyrics Sorry, We don't have lyrics for this song yet. $ rdio lyrics --artist="Guy Clark" And that old time feeling goes sneakin' down the hall Like an old gray cat in winter, keepin' close to the wall And that old time feeling comes stumblin' up the street Like an old salesman kickin' the papers from his feet And that old time feeling draws circles around the block Like old women with no children, holdin' hands with the clock And that old time feeling falls on its face in the park Like an old wino prayin' he can make it till it's dark And that old time feeling comes and goes in the rain Like an old man with his checkers, dyin' to find a game And that old time feeling plays for beer in bars Like an old blues-time picker who don't recall who you are And that old time feeling limps through the night on a crutch Like an old soldier wonderin' if he's paid too much And that old time feeling rocks and spits and cries Like an old lover rememberin' the girl with the clear blue eyes And that old time feeling goes sneakin' down the hall Like an old gray cat in winter, keepin' close to the wall
